+# Cargo Architecture
+
+This document gives a high level overview of Cargo internals. You may
+find it useful if you want to contribute to Cargo or if you are
+interested in the inner workings of Cargo.
+
+The purpose of Cargo is to formalize a canonical Rust workflow, by automating
+the standard tasks associated with distributing software. Cargo simplifies
+structuring a new project, adding dependencies, writing and running unit tests,
+and more.
+
+
+## Subcommands
+
+Cargo is a single binary composed of a set of [`clap`][] subcommands. All subcommands live in
+`src/bin/cargo/commands` directory. `src/bin/cargo/main.rs` is the entry point.
+
+Each subcommand, such as `src/bin/cargo/commands/build.rs`, has its own API
+interface, similarly to Git's, parsing command line options, reading the
+configuration files, discovering the Cargo project in the current directory and
+delegating the actual implementation to one
+of the functions in `src/cargo/ops/mod.rs`. This short file is a good
+place to find out about most of the things that Cargo can do.
+Subcommands are designed to pipe to one another, and custom subcommands make
+Cargo easy to extend and attach tools to.
+
+[`clap`]: https://clap.rs/
+
+
+## Important Data Structures
+
+There are some important data structures which are used throughout
+Cargo.
+
+`Config` is available almost everywhere and holds "global"
+information, such as `CARGO_HOME` or configuration from
+`.cargo/config` files. The `shell` method of `Config` is the entry
+point for printing status messages and other info to the console.
+
+`Workspace` is the description of the workspace for the current
+working directory. Each workspace contains at least one
+`Package`. Each package corresponds to a single `Cargo.toml`, and may
+define several `Target`s, such as the library, binaries, integration
+test or examples. Targets are crates (each target defines a crate
+root, like `src/lib.rs` or `examples/foo.rs`) and are what is actually
+compiled by `rustc`.
+
+A typical package defines the single library target and several
+auxiliary ones. Packages are a unit of dependency in Cargo, and when
+package `foo` depends on package `bar`, that means that each target
+from `foo` needs the library target from `bar`.
+
+`PackageId` is the unique identifier of a (possibly remote)
+package. It consist of three components: name, version and source
+id. Source is the place where the source code for package comes
+from. Typical sources are crates.io, a git repository or a folder on
+the local hard drive.
+
+`Resolve` is the representation of a directed acyclic graph of package
+dependencies, which uses `PackageId`s for nodes. This is the data
+structure that is saved to the lock file. If there is no lockfile,
+Cargo constructs a resolve by finding a graph of packages which
+matches declared dependency specification according to semver.
+
+
+## Persistence
+
+Cargo is a non-daemon command line application, which means that all
+the information used by Cargo must be persisted on the hard drive. The
+main sources of information are `Cargo.toml` and `Cargo.lock` files,
+`.cargo/config` configuration files and the globally shared registry
+of packages downloaded from crates.io, usually located at
+`~/.cargo/registry`. See `src/sources/registry` for the specifics of
+the registry storage format.
+
+
+## Concurrency
+
+Cargo is mostly single threaded. The only concurrency inside a single
+instance of Cargo happens during compilation, when several instances
+of `rustc` are invoked in parallel to build independent
+targets. However there can be several different instances of Cargo
+process running concurrently on the system. Cargo guarantees that this
+is always safe by using file locks when accessing potentially shared
+data like the registry or the target directory.
+
+
+## Tests
+
+Cargo has an impressive test suite located in the `tests` folder. Most
+of the test are integration: a project structure with `Cargo.toml` and
+rust source code is created in a temporary directory, `cargo` binary
+is invoked via `std::process::Command` and then stdout and stderr are
+verified against the expected output. To simplify testing, several
+macros of the form `[MACRO]` are used in the expected output. For
+example, `[..]` matches any string.
+
+To see stdout and stderr streams of the subordinate process, add `.stream()`
+call to the built-up `Execs`:
+
+```rust
+// Before
+p.cargo("run").run();
+
+// After
+p.cargo("run").stream().run();
+```
+
+Alternatively to build and run a custom version of cargo simply run `cargo build`
+and execute `target/debug/cargo`. Note that `+nightly`/`+stable` (and variants),
+being [rustup](https://rustup.rs/) features, won't work when executing the locally
+built cargo binary directly, you have to instead build with `cargo +nightly build`
+and run with `rustup run` (e.g `rustup run nightly
+<path-to-cargo>/target/debug/cargo <args>..`) (or set the `RUSTC` env var to point
+to nightly rustc).
+
+Because the test suite has `#![deny(warnings)]` at times you might find it
+convenient to override this with `RUSTFLAGS`, for example
+`RUSTFLAGS="--cap-lints warn" cargo build`.
+
+## Logging
+
+Cargo uses [`env_logger`](https://docs.rs/env_logger/*/env_logger/), so you can set
+`RUST_LOG` environment variable to get the logs. This is useful both for diagnosing
+bugs in stable Cargo and for local development. Cargo also has internal hierarchical
+profiling infrastructure, which is activated via `CARGO_PROFILE` variable
+
+```
+# Outputs all logs with levels debug and higher
+$ RUST_LOG=debug cargo generate-lockfile
+
+# Don't forget that you can filter by module as well
+$ RUST_LOG=cargo::core::resolver=trace cargo generate-lockfile
+
+# Output first three levels of profiling info
+$ CARGO_PROFILE=3 cargo generate-lockfile
+```

+# Contributing to Cargo
+
+Thank you for your interest in contributing to Cargo! Good places to
+start are this document, [ARCHITECTURE.md](ARCHITECTURE.md), which
+describes the high-level structure of Cargo and [E-easy] bugs on the
+issue tracker.
+
+If you have a general question about Cargo or it's internals, feel free to ask
+on [IRC].
+
+## Code of Conduct
+
+All contributors are expected to follow our [Code of Conduct].
+
+## Bug reports
+
+We can't fix what we don't know about, so please report problems liberally. This
+includes problems with understanding the documentation, unhelpful error messages
+and unexpected behavior.
+
+**If you think that you have identified an issue with Cargo that might compromise
+its users' security, please do not open a public issue on GitHub. Instead,
+we ask you to refer to Rust's [security policy].**
+
+Opening an issue is as easy as following [this link][new-issues] and filling out
+the fields. Here's a template that you can use to file an issue, though it's not
+necessary to use it exactly:
+
+ <short summary of the problem>
+
+ I tried this: <minimal example that causes the problem>
+
+ I expected to see this happen: <explanation>
+
+ Instead, this happened: <explanation>
+
+ I'm using <output of `cargo --version`>
+
+All three components are important: what you did, what you expected, what
+happened instead. Please use https://gist.github.com/ if your examples run long.
+
+
+## Feature requests
+
+Cargo follows the general Rust model of evolution. All major features go through
+an RFC process. Therefore, before opening a feature request issue create a
+Pre-RFC thread on the [internals][irlo] forum to get preliminary feedback.
+Implementing a feature as a [custom subcommand][subcommands] is encouraged as it
+helps demonstrate the demand for the functionality and is a great way to deliver
+a working solution faster as it can iterate outside of cargo's release cadence.
+
+## Working on issues
+
+If you're looking for somewhere to start, check out the [E-easy][E-Easy] and
+[E-mentor][E-mentor] tags.
+
+Feel free to ask for guidelines on how to tackle a problem on [IRC] or open a
+[new issue][new-issues]. This is especially important if you want to add new
+features to Cargo or make large changes to the already existing code-base.
+Cargo's core developers will do their best to provide help.
+
+If you start working on an already-filed issue, post a comment on this issue to
+let people know that somebody is working it. Feel free to ask for comments if
+you are unsure about the solution you would like to submit.
+
+While Cargo does make use of some Rust-features available only through the
+`nightly` toolchain, it must compile on stable Rust. Code added to Cargo
+is encouraged to make use of the latest stable features of the language and
+`stdlib`.
+
+We use the "fork and pull" model [described here][development-models], where
+contributors push changes to their personal fork and create pull requests to
+bring those changes into the source repository. This process is partly
+automated: Pull requests are made against Cargo's master-branch, tested and
+reviewed. Once a change is approved to be merged, a friendly bot merges the
+changes into an internal branch, runs the full test-suite on that branch
+and only then merges into master. This ensures that Cargo's master branch
+passes the test-suite at all times.
+
+Your basic steps to get going:
+
+* Fork Cargo and create a branch from master for the issue you are working on.
+* Please adhere to the code style that you see around the location you are
+working on.
+* [Commit as you go][githelp].
+* Include tests that cover all non-trivial code. The existing tests
+in `test/` provide templates on how to test Cargo's behavior in a
+sandbox-environment. The internal crate `cargotest` provides a vast amount
+of helpers to minimize boilerplate. See [`cargotest/mod.rs`] for an
+introduction to writing tests.
+* Make sure `cargo test` passes. If you do not have the cross-compilers
+installed locally, install them using the instructions returned by
+`cargo test cross_compile::cross_tests` (twice, with `--toolchain nightly`
+added to get the nightly cross target too); alternatively just
+ignore the cross-compile test failures or disable them by
+using `CFG_DISABLE_CROSS_TESTS=1 cargo test`. Note that some tests are enabled
+only on `nightly` toolchain. If you can, test both toolchains.
+* All code changes are expected to comply with the formatting suggested by `rustfmt`.
+You can use `rustup component add --toolchain nightly rustfmt-preview` to install `rustfmt` and use
+`rustfmt +nightly --unstable-features --skip-children` on the changed files to automatically format your code.
+* Push your commits to GitHub and create a pull request against Cargo's
+`master` branch.
+
+## Pull requests
+
+After the pull request is made, a friendly bot will automatically assign a
+reviewer; the review-process will make sure that the proposed changes are
+sound. Please give the assigned reviewer sufficient time, especially during
+weekends. If you don't get a reply, you may poke the core developers on [IRC].
+
+A merge of Cargo's master-branch and your changes is immediately queued
+to be tested after the pull request is made. In case unforeseen
+problems are discovered during this step (e.g. a failure on a platform you
+originally did not develop on), you may ask for guidance. Push additional
+commits to your branch to tackle these problems.
+
+The reviewer might point out changes deemed necessary. Please add them as
+extra commits; this ensures that the reviewer can see what has changed since
+the code was previously reviewed. Large or tricky changes may require several
+passes of review and changes.
+
+Once the reviewer approves your pull request, a friendly bot picks it up
+and [merges][mergequeue] it into Cargo's `master` branch.
+
+## Contributing to the documentation
+
+To contribute to the documentation, all you need to do is change the markdown
+files in the `src/doc` directory. To view the rendered version of changes you
+have made locally, make sure you have `mdbook` installed and run:
+
+```sh
+cd src/doc
+mdbook build
+open book/index.html
+```
+
+To install `mdbook` run `cargo install mdbook`.
+
+
+## Issue Triage
+
+Sometimes an issue will stay open, even though the bug has been fixed. And
+sometimes, the original bug may go stale because something has changed in the
+meantime.
+
+It can be helpful to go through older bug reports and make sure that they are
+still valid. Load up an older issue, double check that it's still true, and
+leave a comment letting us know if it is or is not. The [least recently
+updated sort][lru] is good for finding issues like this.
+
+Contributors with sufficient permissions on the Rust-repository can help by
+adding labels to triage issues:
+
+* Yellow, **A**-prefixed labels state which **area** of the project an issue
+ relates to.
+
+* Magenta, **B**-prefixed labels identify bugs which are **blockers**.
+
+* Light purple, **C**-prefixed labels represent the **category** of an issue.
+ In particular, **C-feature-request** marks *proposals* for new features. If
+ an issue is **C-feature-request**, but is not **Feature accepted** or **I-nominated**,
+ then it was not thoroughly discussed, and might need some additional design
+ or perhaps should be implemented as an external subcommand first. Ping
+ @rust-lang/cargo if you want to send a PR for such issue.
+
+* Dark purple, **Command**-prefixed labels mean the issue has to do with a
+ specific cargo command.
+
+* Green, **E**-prefixed labels explain the level of **experience** or
+ **effort** necessary to fix the issue. [**E-mentor**][E-mentor] issues also
+ have some instructions on how to get started.
+
+* Red, **I**-prefixed labels indicate the **importance** of the issue. The
+ **[I-nominated][]** label indicates that an issue has been nominated for
+ prioritizing at the next triage meeting.
+
+* Purple gray, **O**-prefixed labels are the **operating system** or platform
+ that this issue is specific to.
+
+* Orange, **P**-prefixed labels indicate a bug's **priority**. These labels
+ are only assigned during triage meetings and replace the **[I-nominated][]**
+ label.
+
+* The light orange **relnotes** label marks issues that should be documented in
+ the release notes of the next release.

+ (except as stated in this section) patent license to make, have made,
+ use, offer to sell, sell, import, and otherwise transfer the Work,
+ where such license applies only to those patent claims licensable
+ by such Contributor that are necessarily infringed by their
+ Contribution(s) alone or by combination of their Contribution(s)
+ with the Work to which such Contribution(s) was submitted. If You
+ institute patent litigation against any entity (including a
+ cross-claim or counterclaim in a lawsuit) alleging that the Work
+ or a Contribution incorporated within the Work constitutes direct
+ or contributory patent infringement, then any patent licenses
+ granted to You under this License for that Work shall terminate
+ as of the date such litigation is filed.
+
+4. Redistribution. You may reproduce and distribute copies of the
+ Work or Derivative Works thereof in any medium, with or without
+ modifications, and in Source or Object form, provided that You
+ meet the following conditions:
+
+ (a) You must give any other recipients of the Work or
+ Derivative Works a copy of this License; and
+
+ (b) You must cause any modified files to carry prominent notices
+ stating that You changed the files; and
+
+ (c) You must retain, in the Source form of any Derivative Works
+ that You distribute, all copyright, patent, trademark, and
+ attribution notices from the Source form of the Work,
+ excluding those notices that do not pertain to any part of
+ the Derivative Works; and
+
+ (d) If the Work includes a "NOTICE" text file as part of its
+ distribution, then any Derivative Works that You distribute must
+ include a readable copy of the attribution notices contained
+ within such NOTICE file, excluding those notices that do not
+ pertain to any part of the Derivative Works, in at least one
+ of the following places: within a NOTICE text file distributed
+ as part of the Derivative Works; within the Source form or
+ documentation, if provided along with the Derivative Works; or,
+ within a display generated by the Derivative Works, if and
+ wherever such third-party notices normally appear. The contents
+ of the NOTICE file are for informational purposes only and
+ do not modify the License. You may add Your own attribution
+ notices within Derivative Works that You distribute, alongside
+ or as an addendum to the NOTICE text from the Work, provided
+ that such additional attribution notices cannot be construed
+ as modifying the License.
+
+ You may add Your own copyright statement to Your modifications and
+ may provide additional or different license terms and conditions
+ for use, reproduction, or distribution of Your modifications, or
+ for any such Derivative Works as a whole, provided Your use,
+ reproduction, and distribution of the Work otherwise complies with
+ the conditions stated in this License.
+
+5. Submission of Contributions. Unless You explicitly state otherwise,
+ any Contribution intentionally submitted for inclusion in the Work
+ by You to the Licensor shall be under the terms and conditions of
+ this License, without any additional terms or conditions.
+ Notwithstanding the above, nothing herein shall supersede or modify
+ the terms of any separate license agreement you may have executed
+ with Licensor regarding such Contributions.
+
+6. Trademarks. This License does not grant permission to use the trade
+ names, trademarks, service marks, or product names of the Licensor,
+ except as required for reasonable and customary use in describing the
+ origin of the Work and reproducing the content of the NOTICE file.
+
+7. Disclaimer of Warranty. Unless required by applicable law or
+ agreed to in writing, Licensor provides the Work (and each
+ Contributor provides its Contributions) on an "AS IS" BASIS,
+ WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+ implied, including, without limitation, any warranties or conditions
+ of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+ PARTICULAR PURPOSE. You are solely responsible for determining the
+ appropriateness of using or redistributing the Work and assume any
+ risks associated with Your exercise of permissions under this License.
+
+8. Limitation of Liability. In no event and under no legal theory,
+ whether in tort (including negligence), contract, or otherwise,
+ unless required by applicable law (such as deliberate and grossly
+ negligent acts) or agreed to in writing, shall any Contributor be
+ liable to You for damages, including any direct, indirect, special,
+ incidental, or consequential damages of any character arising as a
+ result of this License or out of the use or inability to use the
+ Work (including but not limited to damages for loss of goodwill,
+ work stoppage, computer failure or malfunction, or any and all
+ other commercial damages or losses), even if such Contributor
+ has been advised of the possibility of such damages.
+
+9. Accepting Warranty or Additional Liability. While redistributing
+ the Work or Derivative Works thereof, You may choose to offer,
+ and charge a fee for, acceptance of support, warranty, indemnity,
+ or other liability obligations and/or rights consistent with this
+ License. However, in accepting such obligations, You may act only
+ on Your own behalf and on Your sole responsibility, not on behalf
+ of any other Contributor, and only if You agree to indemnify,
+ defend, and hold each Contributor harmless for any liability
+ incurred by, or claims asserted against, such Contributor by reason
+ of your accepting any such warranty or additional liability.

+
+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+ freedom to share and change it. By contrast, the GNU General Public
+ License is intended to guarantee your freedom to share and change free
+ software--to make sure the software is free for all its users. This
+ General Public License applies to most of the Free Software
+ Foundation's software and to any other program whose authors commit to
+ using it. (Some other Free Software Foundation software is covered by
+ the GNU Library General Public License instead.) You can apply it to
+ your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+ price. Our General Public Licenses are designed to make sure that you
+ have the freedom to distribute copies of free software (and charge for
+ this service if you wish), that you receive source code or can get it
+ if you want it, that you can change the software or use pieces of it
+ in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+ anyone to deny you these rights or to ask you to surrender the rights.
+ These restrictions translate to certain responsibilities for you if you
+ distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+ gratis or for a fee, you must give the recipients all the rights that
+ you have. You must make sure that they, too, receive or can get the
+ source code. And you must show them these terms so they know their
+ rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+ (2) offer you this license which gives you legal permission to copy,
+ distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+ that everyone understands that there is no warranty for this free
+ software. If the software is modified by someone else and passed on, we
+ want its recipients to know that what they have is not the original, so
+ that any problems introduced by others will not reflect on the original
+ authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+ patents. We wish to avoid the danger that redistributors of a free
+ program will individually obtain patent licenses, in effect making the
+ program proprietary. To prevent this, we have made it clear that any
+ patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+ modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+ a notice placed by the copyright holder saying it may be distributed
+ under the terms of this General Public License. The "Program", below,
+ refers to any such program or work, and a "work based on the Program"
+ means either the Program or any derivative work under copyright law:
+ that is to say, a work containing the Program or a portion of it,
+ either verbatim or with modifications and/or translated into another
+ language. (Hereinafter, translation is included without limitation in
+ the term "modification".) Each licensee is addressed as "you".
+
+ Activities other than copying, distribution and modification are not
+ covered by this License; they are outside its scope. The act of
+ running the Program is not restricted, and the output from the Program
+ is covered only if its contents constitute a work based on the
+ Program (independent of having been made by running the Program).
+ Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+ source code as you receive it, in any medium, provided that you
+ conspicuously and appropriately publish on each copy an appropriate
+ copyright notice and disclaimer of warranty; keep intact all the
+ notices that refer to this License and to the absence of any warranty;
+ and give any other recipients of the Program a copy of this License
+ along with the Program.
+
+ You may charge a fee for the physical act of transferring a copy, and
+ you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+ of it, thus forming a work based on the Program, and copy and
+ distribute such modifications or work under the terms of Section 1
+ above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+ These requirements apply to the modified work as a whole. If
+ identifiable sections of that work are not derived from the Program,
+ and can be reasonably considered independent and separate works in
+ themselves, then this License, and its terms, do not apply to those
+ sections when you distribute them as separate works. But when you
+ distribute the same sections as part of a whole which is a work based
+ on the Program, the distribution of the whole must be on the terms of
+ this License, whose permissions for other licensees extend to the
+ entire whole, and thus to each and every part regardless of who wrote it.
+
+ Thus, it is not the intent of this section to claim rights or contest
+ your rights to work written entirely by you; rather, the intent is to
+ exercise the right to control the distribution of derivative or
+ collective works based on the Program.
+
+ In addition, mere aggregation of another work not based on the Program
+ with the Program (or with a work based on the Program) on a volume of
+ a storage or distribution medium does not bring the other work under
+ the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+ under Section 2) in object code or executable form under the terms of
+ Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+ The source code for a work means the preferred form of the work for
+ making modifications to it. For an executable work, complete source
+ code means all the source code for all modules it contains, plus any
+ associated interface definition files, plus the scripts used to
+ control compilation and installation of the executable. However, as a
+ special exception, the source code distributed need not include
+ anything that is normally distributed (in either source or binary
+ form) with the major components (compiler, kernel, and so on) of the
+ operating system on which the executable runs, unless that component
+ itself accompanies the executable.
+
+ If distribution of executable or object code is made by offering
+ access to copy from a designated place, then offering equivalent
+ access to copy the source code from the same place counts as
+ distribution of the source code, even though third parties are not
+ compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+ except as expressly provided under this License. Any attempt
+ otherwise to copy, modify, sublicense or distribute the Program is
+ void, and will automatically terminate your rights under this License.
+ However, parties who have received copies, or rights, from you under
+ this License will not have their licenses terminated so long as such
+ parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+ signed it. However, nothing else grants you permission to modify or
+ distribute the Program or its derivative works. These actions are
+ prohibited by law if you do not accept this License. Therefore, by
+ modifying or distributing the Program (or any work based on the
+ Program), you indicate your acceptance of this License to do so, and
+ all its terms and conditions for copying, distributing or modifying
+ the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+ Program), the recipient automatically receives a license from the
+ original licensor to copy, distribute or modify the Program subject to
+ these terms and conditions. You may not impose any further
+ restrictions on the recipients' exercise of the rights granted herein.
+ You are not responsible for enforcing compliance by third parties to
+ this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+ infringement or for any other reason (not limited to patent issues),
+ conditions are imposed on you (whether by court order, agreement or
+ otherwise) that contradict the conditions of this License, they do not
+ excuse you from the conditions of this License. If you cannot
+ distribute so as to satisfy simultaneously your obligations under this
+ License and any other pertinent obligations, then as a consequence you
+ may not distribute the Program at all. For example, if a patent
+ license would not permit royalty-free redistribution of the Program by
+ all those who receive copies directly or indirectly through you, then
+ the only way you could satisfy both it and this License would be to
+ refrain entirely from distribution of the Program.
+
+ If any portion of this section is held invalid or unenforceable under
+ any particular circumstance, the balance of the section is intended to
+ apply and the section as a whole is intended to apply in other
+ circumstances.
+
+ It is not the purpose of this section to induce you to infringe any
+ patents or other property right claims or to contest validity of any
+ such claims; this section has the sole purpose of protecting the
+ integrity of the free software distribution system, which is
+ implemented by public license practices. Many people have made
+ generous contributions to the wide range of software distributed
+ through that system in reliance on consistent application of that
+ system; it is up to the author/donor to decide if he or she is willing
+ to distribute software through any other system and a licensee cannot
+ impose that choice.
+
+ This section is intended to make thoroughly clear what is believed to
+ be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+ certain countries either by patents or by copyrighted interfaces, the
+ original copyright holder who places the Program under this License
+ may add an explicit geographical distribution limitation excluding
+ those countries, so that distribution is permitted only in or among
+ countries not thus excluded. In such case, this License incorporates
+ the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+ of the General Public License from time to time. Such new versions will
+ be similar in spirit to the present version, but may differ in detail to
+ address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the Program
+ specifies a version number of this License which applies to it and "any
+ later version", you have the option of following the terms and conditions
+ either of that version or of any later version published by the Free
+ Software Foundation. If the Program does not specify a version number of
+ this License, you may choose any version ever published by the Free Software
+ Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+ programs whose distribution conditions are different, write to the author
+ to ask for permission. For software which is copyrighted by the Free
+ Software Foundation, write to the Free Software Foundation; we sometimes
+ make exceptions for this. Our decision will be guided by the two goals
+ of preserving the free status of all derivatives of our free software and
+ of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+ FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+ OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+ PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+ OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+ MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+ TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+ PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+ REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+ WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+ REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+ INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+ OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+ TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+ YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+ PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+ POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+ possible use to the public, the best way to achieve this is to make it
+ free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+ to attach them to the start of each source file to most effectively
+ convey the exclusion of warranty; and each file should have at least
+ the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+
+
+ Also add information on how to contact you by electronic and paper mail.
+
+ If the program is interactive, make it output a short notice like this
+ when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+ The hypothetical commands `show w' and `show c' should show the appropriate
+ parts of the General Public License. Of course, the commands you use may
+ be called something other than `show w' and `show c'; they could even be
+ mouse-clicks or menu items--whatever suits your program.
+
+ You should also get your employer (if you work as a programmer) or your
+ school, if any, to sign a "copyright disclaimer" for the program, if
+ necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.

+ Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ [This is the first released version of the Lesser GPL. It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+ freedom to share and change it. By contrast, the GNU General Public
+ Licenses are intended to guarantee your freedom to share and change
+ free software--to make sure the software is free for all its users.
+
+ This license, the Lesser General Public License, applies to some
+ specially designated software packages--typically libraries--of the
+ Free Software Foundation and other authors who decide to use it. You
+ can use it too, but we suggest you first think carefully about whether
+ this license or the ordinary General Public License is the better
+ strategy to use in any particular case, based on the explanations below.
+
+ When we speak of free software, we are referring to freedom of use,
+ not price. Our General Public Licenses are designed to make sure that
+ you have the freedom to distribute copies of free software (and charge
+ for this service if you wish); that you receive source code or can get
+ it if you want it; that you can change the software and use pieces of
+ it in new free programs; and that you are informed that you can do
+ these things.
+
+ To protect your rights, we need to make restrictions that forbid
+ distributors to deny you these rights or to ask you to surrender these
+ rights. These restrictions translate to certain responsibilities for
+ you if you distribute copies of the library or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+ or for a fee, you must give the recipients all the rights that we gave
+ you. You must make sure that they, too, receive or can get the source
+ code. If you link other code with the library, you must provide
+ complete object files to the recipients, so that they can relink them
+ with the library after making changes to the library and recompiling
+ it. And you must show them these terms so they know their rights.
+
+ We protect your rights with a two-step method: (1) we copyright the
+ library, and (2) we offer you this license, which gives you legal
+ permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+ there is no warranty for the free library. Also, if the library is
+ modified by someone else and passed on, the recipients should know
+ that what they have is not the original version, so that the original
+ author's reputation will not be affected by problems that might be
+ introduced by others.
+
+ Finally, software patents pose a constant threat to the existence of
+ any free program. We wish to make sure that a company cannot
+ effectively restrict the users of a free program by obtaining a
+ restrictive license from a patent holder. Therefore, we insist that
+ any patent license obtained for a version of the library must be
+ consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ ordinary GNU General Public License. This license, the GNU Lesser
+ General Public License, applies to certain designated libraries, and
+ is quite different from the ordinary General Public License. We use
+ this license for certain libraries in order to permit linking those
+ libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+ a shared library, the combination of the two is legally speaking a
+ combined work, a derivative of the original library. The ordinary
+ General Public License therefore permits such linking only if the
+ entire combination fits its criteria of freedom. The Lesser General
+ Public License permits more lax criteria for linking other code with
+ the library.
+
+ We call this license the "Lesser" General Public License because it
+ does Less to protect the user's freedom than the ordinary General
+ Public License. It also provides other free software developers Less
+ of an advantage over competing non-free programs. These disadvantages
+ are the reason we use the ordinary General Public License for many
+ libraries. However, the Lesser license provides advantages in certain
+ special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+ encourage the widest possible use of a certain library, so that it becomes
+ a de-facto standard. To achieve this, non-free programs must be
+ allowed to use the library. A more frequent case is that a free
+ library does the same job as widely used non-free libraries. In this
+ case, there is little to gain by limiting the free library to free
+ software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+ programs enables a greater number of people to use a large body of
+ free software. For example, permission to use the GNU C Library in
+ non-free programs enables many more people to use the whole GNU
+ operating system, as well as its variant, the GNU/Linux operating
+ system.
+
+ Although the Lesser General Public License is Less protective of the
+ users' freedom, it does ensure that the user of a program that is
+ linked with the Library has the freedom and the wherewithal to run
+ that program using a modified version of the Library.
+
+ The precise terms and conditions for copying, distribution and
+ modification follow. Pay close attention to the difference between a
+ "work based on the library" and a "work that uses the library". The
+ former contains code derived from the library, whereas the latter must
+ be combined with the library in order to run.
+
+ GNU LESSER GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library or other
+ program which contains a notice placed by the copyright holder or
+ other authorized party saying it may be distributed under the terms of
+ this Lesser General Public License (also called "this License").
+ Each licensee is addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+ prepared so as to be conveniently linked with application programs
+ (which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+ which has been distributed under these terms. A "work based on the
+ Library" means either the Library or any derivative work under
+ copyright law: that is to say, a work containing the Library or a
+ portion of it, either verbatim or with modifications and/or translated
+ straightforwardly into another language. (Hereinafter, translation is
+ included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+ making modifications to it. For a library, complete source code means
+ all the source code for all modules it contains, plus any associated
+ interface definition files, plus the scripts used to control compilation
+ and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+ covered by this License; they are outside its scope. The act of
+ running a program using the Library is not restricted, and output from
+ such a program is covered only if its contents constitute a work based
+ on the Library (independent of the use of the Library in a tool for
+ writing it). Whether that is true depends on what the Library does
+ and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+ complete source code as you receive it, in any medium, provided that
+ you conspicuously and appropriately publish on each copy an
+ appropriate copyright notice and disclaimer of warranty; keep intact
+ all the notices that refer to this License and to the absence of any
+ warranty; and distribute a copy of this License along with the
+ Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+ and you may at your option offer warranty protection in exchange for a
+ fee.
+
+ 2. You may modify your copy or copies of the Library or any portion
+ of it, thus forming a work based on the Library, and copy and
+ distribute such modifications or work under the terms of Section 1
+ above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+ These requirements apply to the modified work as a whole. If
+ identifiable sections of that work are not derived from the Library,
+ and can be reasonably considered independent and separate works in
+ themselves, then this License, and its terms, do not apply to those
+ sections when you distribute them as separate works. But when you
+ distribute the same sections as part of a whole which is a work based
+ on the Library, the distribution of the whole must be on the terms of
+ this License, whose permissions for other licensees extend to the
+ entire whole, and thus to each and every part regardless of who wrote
+ it.
+
+ Thus, it is not the intent of this section to claim rights or contest
+ your rights to work written entirely by you; rather, the intent is to
+ exercise the right to control the distribution of derivative or
+ collective works based on the Library.
+
+ In addition, mere aggregation of another work not based on the Library
+ with the Library (or with a work based on the Library) on a volume of
+ a storage or distribution medium does not bring the other work under
+ the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+ License instead of this License to a given copy of the Library. To do
+ this, you must alter all the notices that refer to this License, so
+ that they refer to the ordinary GNU General Public License, version 2,
+ instead of to this License. (If a newer version than version 2 of the
+ ordinary GNU General Public License has appeared, then you can specify
+ that version instead if you wish.) Do not make any other change in
+ these notices.
+
+ Once this change is made in a given copy, it is irreversible for
+ that copy, so the ordinary GNU General Public License applies to all
+ subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+ the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+ derivative of it, under Section 2) in object code or executable form
+ under the terms of Sections 1 and 2 above provided that you accompany
+ it with the complete corresponding machine-readable source code, which
+ must be distributed under the terms of Sections 1 and 2 above on a
+ medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+ from a designated place, then offering equivalent access to copy the
+ source code from the same place satisfies the requirement to
+ distribute the source code, even though third parties are not
+ compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+ Library, but is designed to work with the Library by being compiled or
+ linked with it, is called a "work that uses the Library". Such a
+ work, in isolation, is not a derivative work of the Library, and
+ therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+ creates an executable that is a derivative of the Library (because it
+ contains portions of the Library), rather than a "work that uses the
+ library". The executable is therefore covered by this License.
+ Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+ that is part of the Library, the object code for the work may be a
+ derivative work of the Library even though the source code is not.
+ Whether this is true is especially significant if the work can be
+ linked without the Library, or if the work is itself a library. The
+ threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+ structure layouts and accessors, and small macros and small inline
+ functions (ten lines or less in length), then the use of the object
+ file is unrestricted, regardless of whether it is legally a derivative
+ work. (Executables containing this object code plus portions of the
+ Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+ distribute the object code for the work under the terms of Section 6.
+ Any executables containing that work also fall under Section 6,
+ whether or not they are linked directly with the Library itself.
+
+ 6. As an exception to the Sections above, you may also combine or
+ link a "work that uses the Library" with the Library to produce a
+ work containing portions of the Library, and distribute that work
+ under terms of your choice, provided that the terms permit
+ modification of the work for the customer's own use and reverse
+ engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+ Library is used in it and that the Library and its use are covered by
+ this License. You must supply a copy of this License. If the work
+ during execution displays copyright notices, you must include the
+ copyright notice for the Library among them, as well as a reference
+ directing the user to the copy of this License. Also, you must do one
+ of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a
+ copy of the library already present on the user's computer system,
+ rather than copying library functions into the executable, and (2)
+ will operate properly with a modified version of the library, if
+ the user installs one, as long as the modified version is
+ interface-compatible with the version that the work was made with.
+
+ c) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ d) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ e) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+ Library" must include any data and utility programs needed for
+ reproducing the executable from it. However, as a special exception,
+ the materials to be distributed need not include anything that is
+ normally distributed (in either source or binary form) with the major
+ components (compiler, kernel, and so on) of the operating system on
+ which the executable runs, unless that component itself accompanies
+ the executable.
+
+ It may happen that this requirement contradicts the license
+ restrictions of other proprietary libraries that do not normally
+ accompany the operating system. Such a contradiction means you cannot
+ use both them and the Library together in an executable that you
+ distribute.
+
+ 7. You may place library facilities that are a work based on the
+ Library side-by-side in a single library together with other library
+ facilities not covered by this License, and distribute such a combined
+ library, provided that the separate distribution of the work based on
+ the Library and of the other library facilities is otherwise
+ permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+ the Library except as expressly provided under this License. Any
+ attempt otherwise to copy, modify, sublicense, link with, or
+ distribute the Library is void, and will automatically terminate your
+ rights under this License. However, parties who have received copies,
+ or rights, from you under this License will not have their licenses
+ terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+ signed it. However, nothing else grants you permission to modify or
+ distribute the Library or its derivative works. These actions are
+ prohibited by law if you do not accept this License. Therefore, by
+ modifying or distributing the Library (or any work based on the
+ Library), you indicate your acceptance of this License to do so, and
+ all its terms and conditions for copying, distributing or modifying
+ the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+ Library), the recipient automatically receives a license from the
+ original licensor to copy, distribute, link with or modify the Library
+ subject to these terms and conditions. You may not impose any further
+ restrictions on the recipients' exercise of the rights granted herein.
+ You are not responsible for enforcing compliance by third parties with
+ this License.
+
+ 11. If, as a consequence of a court judgment or allegation of patent
+ infringement or for any other reason (not limited to patent issues),
+ conditions are imposed on you (whether by court order, agreement or
+ otherwise) that contradict the conditions of this License, they do not
+ excuse you from the conditions of this License. If you cannot
+ distribute so as to satisfy simultaneously your obligations under this
+ License and any other pertinent obligations, then as a consequence you
+ may not distribute the Library at all. For example, if a patent
+ license would not permit royalty-free redistribution of the Library by
+ all those who receive copies directly or indirectly through you, then
+ the only way you could satisfy both it and this License would be to
+ refrain entirely from distribution of the Library.
+
+ If any portion of this section is held invalid or unenforceable under any
+ particular circumstance, the balance of the section is intended to apply,
+ and the section as a whole is intended to apply in other circumstances.
+
+ It is not the purpose of this section to induce you to infringe any
+ patents or other property right claims or to contest validity of any
+ such claims; this section has the sole purpose of protecting the
+ integrity of the free software distribution system which is
+ implemented by public license practices. Many people have made
+ generous contributions to the wide range of software distributed
+ through that system in reliance on consistent application of that
+ system; it is up to the author/donor to decide if he or she is willing
+ to distribute software through any other system and a licensee cannot
+ impose that choice.
+
+ This section is intended to make thoroughly clear what is believed to
+ be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+ certain countries either by patents or by copyrighted interfaces, the
+ original copyright holder who places the Library under this License may add
+ an explicit geographical distribution limitation excluding those countries,
+ so that distribution is permitted only in or among countries not thus
+ excluded. In such case, this License incorporates the limitation as if
+ written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+ versions of the Lesser General Public License from time to time.
+ Such new versions will be similar in spirit to the present version,
+ but may differ in detail to address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the Library
+ specifies a version number of this License which applies to it and
+ "any later version", you have the option of following the terms and
+ conditions either of that version or of any later version published by
+ the Free Software Foundation. If the Library does not specify a
+ license version number, you may choose any version ever published by
+ the Free Software Foundation.
+
+ 14. If you wish to incorporate parts of the Library into other free
+ programs whose distribution conditions are incompatible with these,
+ write to the author to ask for permission. For software which is
+ copyrighted by the Free Software Foundation, write to the Free
+ Software Foundation; we sometimes make exceptions for this. Our
+ decision will be guided by the two goals of preserving the free status
+ of all derivatives of our free software and of promoting the sharing
+ and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+ WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+ EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+ OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+ KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+ IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+ PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+ LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+ THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+ WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+ AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+ FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+ CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+ LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+ RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+ FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+ SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+ DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Libraries
+
+ If you develop a new library, and you want it to be of the greatest
+ possible use to the public, we recommend making it free software that
+ everyone can redistribute and change. You can do so by permitting
+ redistribution under these terms (or, alternatively, under the terms of the
+ ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+ safest to attach them to the start of each source file to most effectively
+ convey the exclusion of warranty; and each file should have at least the
+ "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the library's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>

+ Also add information on how to contact you by electronic and paper mail.

+# Cargo
+
+Cargo downloads your Rust project’s dependencies and compiles your project.
+
+Learn more at https://doc.rust-lang.org/cargo/
+
+## Code Status
+
+[](https://travis-ci.org/rust-lang/cargo)
+[](https://ci.appveyor.com/project/rust-lang-libs/cargo)
+
+Code documentation: https://docs.rs/cargo/
+
+## Installing Cargo
+
+Cargo is distributed by default with Rust, so if you've got `rustc` installed
+locally you probably also have `cargo` installed locally.
+
+## Compiling from Source
+
+Cargo requires the following tools and packages to build:
+
+* `python`
+* `curl` (on Unix)
+* `cmake`
+* OpenSSL headers (only for Unix, this is the `libssl-dev` package on ubuntu)
+* `cargo` and `rustc`
+
+First, you'll want to check out this repository
+
+```
+git clone https://github.com/rust-lang/cargo
+cd cargo
+```
+
+With `cargo` already installed, you can simply run:
+
+```
+cargo build --release
+```
+
+## Adding new subcommands to Cargo
+
+Cargo is designed to be extensible with new subcommands without having to modify
+Cargo itself. See [the Wiki page][third-party-subcommands] for more details and
+a list of known community-developed subcommands.
+
+[third-party-subcommands]: https://github.com/rust-lang/cargo/wiki/Third-party-cargo-subcommands
+
+
+## Releases
+
+High level release notes are available as part of [Rust's release notes][rel].
+Cargo releases coincide with Rust releases.
+
+[rel]: https://github.com/rust-lang/rust/blob/master/RELEASES.md
+
+## Reporting issues
+
+Found a bug? We'd love to know about it!
+
+Please report all issues on the GitHub [issue tracker][issues].
+
+[issues]: https://github.com/rust-lang/cargo/issues
+
+## Contributing
+
+See [CONTRIBUTING.md](CONTRIBUTING.md). You may also find the architecture
+documentation useful ([ARCHITECTURE.md](ARCHITECTURE.md)).

+This Cargo subcommand will automatically take rustc's suggestions from

+The `cargo fix` subcommand is also being developed for the Rust 2018 edition
+to provide code the ability to easily opt-in to the new edition without having
+to worry about any breakage.
+
+Executing `cargo fix` will under the hood execute `cargo check`. Any warnings
+applicable to your crate will be automatically fixed (if possible) and all
+remaining warnings will be displayed when the check process is finished. For
+example if you'd like to prepare for the 2018 edition, you can do so by
+executing:
+
+ cargo fix --edition
+
+which behaves the same as `cargo check --all-targets`. Similarly if you'd like
+to fix code for different platforms you can do:
+
+ cargo fix --edition --target x86_64-pc-windows-gnu
+
+or if your crate has optional features:
+
+ cargo fix --edition --no-default-features --features foo
+
+If you encounter any problems with `cargo fix` or otherwise have any questions

+ "\
+This command manages Cargo's local set of installed binary crates. Only packages
+which have [[bin]] targets can be installed, and all binaries are installed into
+the installation root's `bin` folder. The installation root is determined, in
+order of precedence, by `--root`, `$CARGO_INSTALL_ROOT`, the `install.root`
+configuration key, and finally the home directory (which is either
+`$CARGO_HOME` if set or `$HOME/.cargo` by default).
+
+There are multiple sources from which a crate can be installed. The default
+location is crates.io but the `--git` and `--path` flags can change this source.
+If the source contains more than one package (such as crates.io or a git
+repository with multiple crates) the `<crate>` argument is required to indicate
+which crate should be installed.
+
+Crates from crates.io can optionally specify the version they wish to install
+via the `--vers` flags, and similarly packages from git repositories can
+optionally specify the branch, tag, or revision that should be installed. If a
+crate has multiple binaries, the `--bin` argument can selectively install only
+one of them, and if you'd rather install examples the `--example` argument can
+be used as well.
+
+By default cargo will refuse to overwrite existing binaries. The `--force` flag
+enables overwriting existing binaries. Thus you can reinstall a crate with
+`cargo install --force <crate>`.
+
+Omitting the <crate> specification entirely will
+install the crate in the current directory. That is, `install` is equivalent to
+the more explicit `install --path .`. This behaviour is deprecated, and no
+longer supported as of the Rust 2018 edition.
+
+If the source is crates.io or `--git` then by default the crate will be built
+in a temporary target directory. To avoid this, the target directory can be
+specified by setting the `CARGO_TARGET_DIR` environment variable to a relative
+path. In particular, this can be useful for caching build artifacts on
+continuous integration systems.",

+The test filtering argument `TESTNAME` and all the arguments following the
+two dashes (`--`) are passed to the test binaries and thus to libtest
+(rustc's built in unit-test and micro-benchmarking framework). If you're
+passing arguments to both Cargo and the binary, the ones after `--` go to the
+binary, the ones before go to Cargo. For details about libtest's arguments see
+the output of `cargo test -- --help`. As an example, this will run all
+tests with `foo` in their name on 3 threads in parallel:
+
+ cargo test foo -- --test-threads 3
+
+If the --package argument is given, then SPEC is a package id specification
+which indicates which package should be tested. If it is not given, then the
+current package is tested. For more information on SPEC and its format, see the
+`cargo help pkgid` command.
+
+All packages in the workspace are tested if the `--all` flag is supplied. The
+`--all` flag is automatically assumed for a virtual manifest.
+Note that `--exclude` has to be specified in conjunction with the `--all` flag.
+
+The --jobs argument affects the building of the test executable but does
+not affect how many jobs are used when running the tests. The default value
+for the --jobs argument is the number of CPUs. If you want to control the
+number of simultaneous running test cases, pass the `--test-threads` option
+to the test binaries:
+
+ cargo test -- --test-threads=1
+
+Compilation can be configured via the `test` profile in the manifest.
+
+By default the rust test harness hides output from test execution to
+keep results readable. Test output can be recovered (e.g. for debugging)
+by passing `--nocapture` to the test binaries:
+
+ cargo test -- --nocapture
+
+To get the list of all options available for the test binaries use this:

+//! Constructs the dependency graph for compilation.
+//!
+//! Rust code is typically organized as a set of Cargo packages. The
+//! dependencies between the packages themselves are stored in the
+//! `Resolve` struct. However, we can't use that information as is for
+//! compilation! A package typically contains several targets, or crates,
+//! and these targets has inter-dependencies. For example, you need to
+//! compile the `lib` target before the `bin` one, and you need to compile
+//! `build.rs` before either of those.
+//!
+//! So, we need to lower the `Resolve`, which specifies dependencies between
+//! *packages*, to a graph of dependencies between their *targets*, and this
+//! is exactly what this module is doing! Well, almost exactly: another
+//! complication is that we might want to compile the same target several times
+//! (for example, with and without tests), so we actually build a dependency
+//! graph of `Unit`s, which capture these properties.

+//! Support for nightly features in Cargo itself
+//!
+//! This file is the version of `feature_gate.rs` in upstream Rust for Cargo
+//! itself and is intended to be the avenue for which new features in Cargo are
+//! gated by default and then eventually stabilized. All known stable and
+//! unstable features are tracked in this file.
+//!
+//! If you're reading this then you're likely interested in adding a feature to
+//! Cargo, and the good news is that it shouldn't be too hard! To do this you'll
+//! want to follow these steps:
+//!
+//! 1. Add your feature. Do this by searching for "look here" in this file and
+//! expanding the macro invocation that lists all features with your new
+//! feature.
+//!
+//! 2. Find the appropriate place to place the feature gate in Cargo itself. If
+//! you're extending the manifest format you'll likely just want to modify
+//! the `Manifest::feature_gate` function, but otherwise you may wish to
+//! place the feature gate elsewhere in Cargo.
+//!
+//! 3. To actually perform the feature gate, you'll want to have code that looks
+//! like:
+//!
+//! ```rust,ignore
+//! use core::{Feature, Features};
+//!
+//! let feature = Feature::launch_into_space();
+//! package.manifest().features().require(feature).chain_err(|| {
+//! "launching Cargo into space right now is unstable and may result in \
+//! unintended damage to your codebase, use with caution"
+//! })?;
+//! ```
+//!
+//! Notably you'll notice the `require` function called with your `Feature`, and
+//! then you use `chain_err` to tack on more context for why the feature was
+//! required when the feature isn't activated.
+//!
+//! 4. Update the unstable documentation at
+//! `src/doc/src/reference/unstable.md` to include a short description of
+//! how to use your new feature. When the feature is stabilized, be sure
+//! that the Cargo Guide or Reference is updated to fully document the
+//! feature and remove the entry from the Unstable section.
+//!
+//! And hopefully that's it! Bear with us though that this is, at the time of
+//! this writing, a very new feature in Cargo. If the process differs from this
+//! we'll be sure to update this documentation!

+/// 3. (optional) Add a new parsing function to parse your datatype. As of now

+//! Resolution of the entire dependency graph for a crate
+//!
+//! This module implements the core logic in taking the world of crates and
+//! constraints and creating a resolved graph with locked versions for all
+//! crates and their dependencies. This is separate from the registry module
+//! which is more worried about discovering crates from various sources, this
+//! module just uses the Registry trait as a source to learn about crates from.
+//!
+//! Actually solving a constraint graph is an NP-hard problem. This algorithm
+//! is basically a nice heuristic to make sure we get roughly the best answer
+//! most of the time. The constraints that we're working with are:
+//!
+//! 1. Each crate can have any number of dependencies. Each dependency can
+//! declare a version range that it is compatible with.
+//! 2. Crates can be activated with multiple version (e.g. show up in the
+//! dependency graph twice) so long as each pairwise instance have
+//! semver-incompatible versions.
+//!
+//! The algorithm employed here is fairly simple, we simply do a DFS, activating
+//! the "newest crate" (highest version) first and then going to the next
+//! option. The heuristics we employ are:
+//!
+//! * Never try to activate a crate version which is incompatible. This means we
+//! only try crates which will actually satisfy a dependency and we won't ever
+//! try to activate a crate that's semver compatible with something else
+//! activated (as we're only allowed to have one) nor try to activate a crate
+//! that has the same links attribute as something else
+//! activated.
+//! * Always try to activate the highest version crate first. The default
+//! dependency in Cargo (e.g. when you write `foo = "0.1.2"`) is
+//! semver-compatible, so selecting the highest version possible will allow us
+//! to hopefully satisfy as many dependencies at once.
+//!
+//! Beyond that, what's implemented below is just a naive backtracking version
+//! which should in theory try all possible combinations of dependencies and
+//! versions to see if one works. The first resolution that works causes
+//! everything to bail out immediately and return success, and only if *nothing*
+//! works do we actually return an error up the stack.
+//!
+//! ## Performance
+//!
+//! Note that this is a relatively performance-critical portion of Cargo. The
+//! data that we're processing is proportional to the size of the dependency
+//! graph, which can often be quite large (e.g. take a look at Servo). To make
+//! matters worse the DFS algorithm we're implemented is inherently quite
+//! inefficient. When we add the requirement of backtracking on top it means
+//! that we're implementing something that probably shouldn't be allocating all
+//! over the place.

+ // `true`, whereas `keep(foo)` will return `true` (roughly).
+ //
+ // This isn't actually quite what we want, however. Instead we want to
+ // further refine this `keep` function with *all transitive dependencies* of
+ // the packages we're not keeping. For example consider a case like this:
+ //
+ // * There's a crate `log`
+ // * There's a crate `serde` which depends on `log`
+ //
+ // Let's say we then run `cargo update -p serde`. This may *also* want to

+ // the `log` crate itself, but we will inform the registry "please prefer
+ // this version of `log`". That way if our newer version of serde works with
+ // the older version of `log`, we conservatively won't update `log`. If,
+ // however, nothing else in the dependency graph depends on `log` and the
+ // newer version of `serde` requires a new version of `log` it'll get pulled
+ // in (as we didn't accidentally lock it to an old version).
+ //
+ // Additionally here we process all path dependencies listed in the previous
+ // resolve. They can not only have their dependencies change but also
+ // the versions of the package change as well. If this ends up happening
+ // then we want to make sure we don't lock a package id node that doesn't
+ // actually exist. Note that we don't do transitive visits of all the
+ // package's dependencies here as that'll be covered below to poison those

+
+ // Ok but the above loop isn't the entire story! Updates to the dependency
+ // graph can come from two locations, the `cargo update` command or
+ // manifests themselves. For example a manifest on the filesystem may
+ // have been updated to have an updated version requirement on `serde`. In
+ // this case both `keep(serde)` and `keep(log)` return `true` (the `keep`
+ // that's an argument to this function). We, however, don't want to keep
+ // either of those! Otherwise we'll get obscure resolve errors about locked
+ // versions.
+ //
+ // To solve this problem we iterate over all packages with path sources
+ // (aka ones with manifests that are changing) and take a look at all of
+ // their dependencies. If any dependency does not match something in the
+ // previous lock file, then we're guaranteed that the main resolver will
+ // update the source of this dependency no matter what. Knowing this we
+ // poison all packages from the same source, forcing them all to get
+ // updated.
+ //
+ // This may seem like a heavy hammer, and it is! It means that if you change

+ // because the first candidate the resolver picks is the previously locked
+ // version, and only if that fails to activate to we move on and try
+ // a different version. (giving the guise of conservative updates)
+ //
+ // For example let's say we had `serde = "0.1"` written in our lock file.
+ // When we later edit this to `serde = "0.1.3"` we don't want to lock serde
+ // at its old version, 0.1.1. Instead we want to allow it to update to

+/// callback, then from whatever is configured in git itself, and finally
+/// we fall back to the generic user of `git`.
+///
+/// * If a username/password is allowed, then we fallback to git2-rs's
+/// implementation of the credential helper. This is what is configured
+/// with `credential.helper` in git, and is the interface for the OSX
+/// keychain, for example.
+///
+/// * After the above two have failed, we just kinda grapple attempting to
+/// return *something*.
+///
+/// If any form of authentication fails, libgit2 will repeatedly ask us for
+/// credentials until we give it a reason to not do so. To ensure we don't
+/// just sit here looping forever we keep track of authentications we've
+/// attempted and we don't try the same ones again.

+//! A `Source` for registry-based packages.
+//!
+//! # What's a Registry?
+//!
+//! Registries are central locations where packages can be uploaded to,
+//! discovered, and searched for. The purpose of a registry is to have a
+//! location that serves as permanent storage for versions of a crate over time.
+//!
+//! Compared to git sources, a registry provides many packages as well as many
+//! versions simultaneously. Git sources can also have commits deleted through
+//! rebasings where registries cannot have their versions deleted.
+//!
+//! # The Index of a Registry
+//!
+//! One of the major difficulties with a registry is that hosting so many
+//! packages may quickly run into performance problems when dealing with
+//! dependency graphs. It's infeasible for cargo to download the entire contents
+//! of the registry just to resolve one package's dependencies, for example. As
+//! a result, cargo needs some efficient method of querying what packages are
+//! available on a registry, what versions are available, and what the
+//! dependencies for each version is.
+//!
+//! One method of doing so would be having the registry expose an HTTP endpoint
+//! which can be queried with a list of packages and a response of their
+//! dependencies and versions is returned. This is somewhat inefficient however
+//! as we may have to hit the endpoint many times and we may have already
+//! queried for much of the data locally already (for other packages, for
+//! example). This also involves inventing a transport format between the
+//! registry and Cargo itself, so this route was not taken.
+//!
+//! Instead, Cargo communicates with registries through a git repository
+//! referred to as the Index. The Index of a registry is essentially an easily
+//! query-able version of the registry's database for a list of versions of a
+//! package as well as a list of dependencies for each version.
+//!
+//! Using git to host this index provides a number of benefits:
+//!
+//! * The entire index can be stored efficiently locally on disk. This means
+//! that all queries of a registry can happen locally and don't need to touch
+//! the network.
+//!
+//! * Updates of the index are quite efficient. Using git buys incremental
+//! updates, compressed transmission, etc for free. The index must be updated
+//! each time we need fresh information from a registry, but this is one
+//! update of a git repository that probably hasn't changed a whole lot so
+//! it shouldn't be too expensive.
+//!
+//! Additionally, each modification to the index is just appending a line at
+//! the end of a file (the exact format is described later). This means that
+//! the commits for an index are quite small and easily applied/compressable.
+//!
+//! ## The format of the Index
+//!
+//! The index is a store for the list of versions for all packages known, so its
+//! format on disk is optimized slightly to ensure that `ls registry` doesn't
+//! produce a list of all packages ever known. The index also wants to ensure
+//! that there's not a million files which may actually end up hitting
+//! filesystem limits at some point. To this end, a few decisions were made
+//! about the format of the registry:
+//!
+//! 1. Each crate will have one file corresponding to it. Each version for a
+//! crate will just be a line in this file.
+//! 2. There will be two tiers of directories for crate names, under which
+//! crates corresponding to those tiers will be located.
+//!
+//! As an example, this is an example hierarchy of an index:
+//!
+//! ```notrust
+//! .
+//! ├── 3
+//! │ └── u
+//! │ └── url
+//! ├── bz
+//! │ └── ip
+//! │ └── bzip2
+//! ├── config.json
+//! ├── en
+//! │ └── co
+//! │ └── encoding
+//! └── li
+//! ├── bg
+//! │ └── libgit2
+//! └── nk
+//! └── link-config
+//! ```
+//!
+//! The root of the index contains a `config.json` file with a few entries
+//! corresponding to the registry (see `RegistryConfig` below).
+//!
+//! Otherwise, there are three numbered directories (1, 2, 3) for crates with
+//! names 1, 2, and 3 characters in length. The 1/2 directories simply have the
+//! crate files underneath them, while the 3 directory is sharded by the first
+//! letter of the crate name.
+//!
+//! Otherwise the top-level directory contains many two-letter directory names,
+//! each of which has many sub-folders with two letters. At the end of all these
+//! are the actual crate files themselves.
+//!
+//! The purpose of this layout is to hopefully cut down on `ls` sizes as well as
+//! efficient lookup based on the crate name itself.
+//!
+//! ## Crate files
+//!
+//! Each file in the index is the history of one crate over time. Each line in
+//! the file corresponds to one version of a crate, stored in JSON format (see
+//! the `RegistryPackage` structure below).
+//!
+//! As new versions are published, new lines are appended to this file. The only
+//! modifications to this file that should happen over time are yanks of a
+//! particular version.
+//!
+//! # Downloading Packages
+//!
+//! The purpose of the Index was to provide an efficient method to resolve the
+//! dependency graph for a package. So far we only required one network
+//! interaction to update the registry's repository (yay!). After resolution has
+//! been performed, however we need to download the contents of packages so we
+//! can read the full manifest and build the source code.
+//!
+//! To accomplish this, this source's `download` method will make an HTTP
+//! request per-package requested to download tarballs into a local cache. These
+//! tarballs will then be unpacked into a destination folder.
+//!
+//! Note that because versions uploaded to the registry are frozen forever that
+//! the HTTP download and unpacking can all be skipped if the version has
+//! already been downloaded and unpacked. This caching allows us to only
+//! download a package when absolutely necessary.
+//!
+//! # Filesystem Hierarchy
+//!
+//! Overall, the `$HOME/.cargo` looks like this when talking about the registry:
+//!
+//! ```notrust
+//! # A folder under which all registry metadata is hosted (similar to
+//! # $HOME/.cargo/git)
+//! $HOME/.cargo/registry/
+//!
+//! # For each registry that cargo knows about (keyed by hostname + hash)
+//! # there is a folder which is the checked out version of the index for
+//! # the registry in this location. Note that this is done so cargo can
+//! # support multiple registries simultaneously
+//! index/
+//! registry1-<hash>/
+//! registry2-<hash>/
+//! ...
+//!
+//! # This folder is a cache for all downloaded tarballs from a registry.
+//! # Once downloaded and verified, a tarball never changes.
+//! cache/
+//! registry1-<hash>/<pkg>-<version>.crate
+//! ...
+//!
+//! # Location in which all tarballs are unpacked. Each tarball is known to
+//! # be frozen after downloading, so transitively this folder is also
+//! # frozen once its unpacked (it's never unpacked again)
+//! src/
+//! registry1-<hash>/<pkg>-<version>/...
+//! ...
+//! ```

+//! An implementation of IPC locks, guaranteed to be released if a process dies
+//!
+//! This module implements a locking server/client where the main `cargo fix`
+//! process will start up a server and then all the client processes will
+//! connect to it. The main purpose of this file is to enusre that each crate
+//! (aka file entry point) is only fixed by one process at a time, currently
+//! concurrent fixes can't happen.
+//!
+//! The basic design here is to use a TCP server which is pretty portable across
+//! platforms. For simplicity it just uses threads as well. Clients connect to
+//! the main server, inform the server what its name is, and then wait for the
+//! server to give it the lock (aka write a byte).

+## Frequently Asked Questions
+
+### Is the plan to use GitHub as a package repository?
+
+No. The plan for Cargo is to use [crates.io], like npm or Rubygems do with
+npmjs.org and rubygems.org.
+
+We plan to support git repositories as a source of packages forever,
+because they can be used for early development and temporary patches,
+even when people use the registry as the primary source of packages.
+
+### Why build crates.io rather than use GitHub as a registry?
+
+We think that it’s very important to support multiple ways to download
+packages, including downloading from GitHub and copying packages into
+your package itself.
+
+That said, we think that [crates.io] offers a number of important benefits, and
+will likely become the primary way that people download packages in Cargo.
+
+For precedent, both Node.js’s [npm][1] and Ruby’s [bundler][2] support both a
+central registry model as well as a Git-based model, and most packages
+are downloaded through the registry in those ecosystems, with an
+important minority of packages making use of git-based packages.
+
+[1]: https://www.npmjs.org
+[2]: https://bundler.io
+
+Some of the advantages that make a central registry popular in other
+languages include:
+
+* **Discoverability**. A central registry provides an easy place to look
+ for existing packages. Combined with tagging, this also makes it
+ possible for a registry to provide ecosystem-wide information, such as a
+ list of the most popular or most-depended-on packages.
+* **Speed**. A central registry makes it possible to easily fetch just
+ the metadata for packages quickly and efficiently, and then to
+ efficiently download just the published package, and not other bloat
+ that happens to exist in the repository. This adds up to a significant
+ improvement in the speed of dependency resolution and fetching. As
+ dependency graphs scale up, downloading all of the git repositories bogs
+ down fast. Also remember that not everybody has a high-speed,
+ low-latency Internet connection.
+
+### Will Cargo work with C code (or other languages)?
+
+Yes!
+
+Cargo handles compiling Rust code, but we know that many Rust packages
+link against C code. We also know that there are decades of tooling
+built up around compiling languages other than Rust.
+
+Our solution: Cargo allows a package to [specify a script](reference/build-scripts.html)
+(written in Rust) to run before invoking `rustc`. Rust is leveraged to
+implement platform-specific configuration and refactor out common build
+functionality among packages.
+
+### Can Cargo be used inside of `make` (or `ninja`, or ...)
+
+Indeed. While we intend Cargo to be useful as a standalone way to
+compile Rust packages at the top-level, we know that some people will
+want to invoke Cargo from other build tools.
+
+We have designed Cargo to work well in those contexts, paying attention
+to things like error codes and machine-readable output modes. We still
+have some work to do on those fronts, but using Cargo in the context of
+conventional scripts is something we designed for from the beginning and
+will continue to prioritize.
+
+### Does Cargo handle multi-platform packages or cross-compilation?
+
+Rust itself provides facilities for configuring sections of code based
+on the platform. Cargo also supports [platform-specific
+dependencies][target-deps], and we plan to support more per-platform
+configuration in `Cargo.toml` in the future.
+
+[target-deps]: reference/specifying-dependencies.html#platform-specific-dependencies
+
+In the longer-term, we’re looking at ways to conveniently cross-compile
+packages using Cargo.
+
+### Does Cargo support environments, like `production` or `test`?
+
+We support environments through the use of [profiles][profile] to support:
+
+[profile]: reference/manifest.html#the-profile-sections
+
+* environment-specific flags (like `-g --opt-level=0` for development
+ and `--opt-level=3` for production).
+* environment-specific dependencies (like `hamcrest` for test assertions).
+* environment-specific `#[cfg]`
+* a `cargo test` command
+
+### Does Cargo work on Windows?
+
+Yes!
+
+All commits to Cargo are required to pass the local test suite on Windows.
+If, however, you find a Windows issue, we consider it a bug, so [please file an
+issue][3].
+
+[3]: https://github.com/rust-lang/cargo/issues
+
+### Why do binaries have `Cargo.lock` in version control, but not libraries?
+
+The purpose of a `Cargo.lock` is to describe the state of the world at the time
+of a successful build. It is then used to provide deterministic builds across
+whatever machine is building the package by ensuring that the exact same
+dependencies are being compiled.
+
+This property is most desirable from applications and packages which are at the
+very end of the dependency chain (binaries). As a result, it is recommended that
+all binaries check in their `Cargo.lock`.
+
+For libraries the situation is somewhat different. A library is not only used by
+the library developers, but also any downstream consumers of the library. Users
+dependent on the library will not inspect the library’s `Cargo.lock` (even if it
+exists). This is precisely because a library should **not** be deterministically
+recompiled for all users of the library.
+
+If a library ends up being used transitively by several dependencies, it’s
+likely that just a single copy of the library is desired (based on semver
+compatibility). If Cargo used all of the dependencies' `Cargo.lock` files,
+then multiple copies of the library could be used, and perhaps even a version
+conflict.
+
+In other words, libraries specify semver requirements for their dependencies but
+cannot see the full picture. Only end products like binaries have a full
+picture to decide what versions of dependencies should be used.
+
+### Can libraries use `*` as a version for their dependencies?
+
+**As of January 22nd, 2016, [crates.io] rejects all packages (not just libraries)
+with wildcard dependency constraints.**
+
+While libraries _can_, strictly speaking, they should not. A version requirement
+of `*` says “This will work with every version ever,” which is never going
+to be true. Libraries should always specify the range that they do work with,
+even if it’s something as general as “every 1.x.y version.”
+
+### Why `Cargo.toml`?
+
+As one of the most frequent interactions with Cargo, the question of why the
+configuration file is named `Cargo.toml` arises from time to time. The leading
+capital-`C` was chosen to ensure that the manifest was grouped with other
+similar configuration files in directory listings. Sorting files often puts
+capital letters before lowercase letters, ensuring files like `Makefile` and
+`Cargo.toml` are placed together. The trailing `.toml` was chosen to emphasize
+the fact that the file is in the [TOML configuration
+format](https://github.com/toml-lang/toml).
+
+Cargo does not allow other names such as `cargo.toml` or `Cargofile` to
+emphasize the ease of how a Cargo repository can be identified. An option of
+many possible names has historically led to confusion where one case was handled
+but others were accidentally forgotten.
+
+[crates.io]: https://crates.io/
+
+### How can Cargo work offline?
+
+Cargo is often used in situations with limited or no network access such as
+airplanes, CI environments, or embedded in large production deployments. Users
+are often surprised when Cargo attempts to fetch resources from the network, and
+hence the request for Cargo to work offline comes up frequently.
+
+Cargo, at its heart, will not attempt to access the network unless told to do
+so. That is, if no crates comes from crates.io, a git repository, or some other
+network location, Cargo will never attempt to make a network connection. As a
+result, if Cargo attempts to touch the network, then it's because it needs to
+fetch a required resource.
+
+Cargo is also quite aggressive about caching information to minimize the amount
+of network activity. It will guarantee, for example, that if `cargo build` (or
+an equivalent) is run to completion then the next `cargo build` is guaranteed to
+not touch the network so long as `Cargo.toml` has not been modified in the
+meantime. This avoidance of the network boils down to a `Cargo.lock` existing
+and a populated cache of the crates reflected in the lock file. If either of
+these components are missing, then they're required for the build to succeed and
+must be fetched remotely.
+
+As of Rust 1.11.0 Cargo understands a new flag, `--frozen`, which is an
+assertion that it shouldn't touch the network. When passed, Cargo will
+immediately return an error if it would otherwise attempt a network request.
+The error should include contextual information about why the network request is
+being made in the first place to help debug as well. Note that this flag *does
+not change the behavior of Cargo*, it simply asserts that Cargo shouldn't touch
+the network as a previous command has been run to ensure that network activity
+shouldn't be necessary.

+replacement][replace].

+## First Steps with Cargo
+
+To start a new package with Cargo, use `cargo new`:
+
+```console
+$ cargo new hello_world
+```
+
+Cargo defaults to `--bin` to make a binary program. To make a library, we'd
+pass `--lib`.
+
+Let’s check out what Cargo has generated for us:
+
+```console
+$ cd hello_world
+$ tree .
+.
+├── Cargo.toml
+└── src
+ └── main.rs
+
+1 directory, 2 files
+```
+
+This is all we need to get started. First, let’s check out `Cargo.toml`:
+
+```toml
+[package]
+name = "hello_world"
+version = "0.1.0"
+authors = ["Your Name <you@example.com>"]
+```
+
+This is called a **manifest**, and it contains all of the metadata that Cargo
+needs to compile your package.
+
+Here’s what’s in `src/main.rs`:
+
+```rust
+fn main() {
+ println!("Hello, world!");
+}
+```
+
+Cargo generated a “hello world” for us. Let’s compile it:
+
+```console
+$ cargo build
+ Compiling hello_world v0.1.0 (file:///path/to/package/hello_world)
+```
+
+And then run it:
+
+```console
+$ ./target/debug/hello_world
+Hello, world!
+```
+
+We can also use `cargo run` to compile and then run it, all in one step:
+
+```console
+$ cargo run
+ Fresh hello_world v0.1.0 (file:///path/to/package/hello_world)
+ Running `target/hello_world`
+Hello, world!
+```

+## Getting Started
+
+To get started with Cargo, install Cargo (and Rust) and set up your first crate.
+
+* [Installation](getting-started/installation.html)
+* [First steps with Cargo](getting-started/first-steps.html)
--- /dev/null
+## Installation
+
+### Install Rust and Cargo
+
+The easiest way to get Cargo is to install the current stable release of [Rust]
+by using `rustup`.
+
+On Linux and macOS systems, this is done as follows:
+
+```console
+$ curl -sSf https://static.rust-lang.org/rustup.sh | sh
+```
+
+It will download a script, and start the installation. If everything goes well,
+you’ll see this appear:
+
+```console
+Rust is installed now. Great!
+```
+
+On Windows, download and run [rustup-init.exe]. It will start the installation
+in a console and present the above message on success.
+
+After this, you can use the `rustup` command to also install `beta` or `nightly`
+channels for Rust and Cargo.
+
+For other installation options and information, visit the
+[install][install-rust] page of the Rust website.
+
+### Build and Install Cargo from Source
+
+Alternatively, you can [build Cargo from source][compiling-from-source].
+
+[rust]: https://www.rust-lang.org/
+[rustup-init.exe]: https://win.rustup.rs/
+[install-rust]: https://www.rust-lang.org/install.html
+[compiling-from-source]: https://github.com/rust-lang/cargo#compiling-from-source
--- /dev/null
+## Build cache
+
+Cargo shares build artifacts among all the packages of a single workspace.
+Today, Cargo does not share build results across different workspaces, but
+a similar result can be achieved by using a third party tool, [sccache].
+
+To setup `sccache`, install it with `cargo install sccache` and set
+`RUSTC_WRAPPER` environmental variable to `sccache` before invoking Cargo.
+If you use bash, it makes sense to add `export RUSTC_WRAPPER=sccache` to
+`.bashrc`. Refer to sccache documentation for more details.
+
+[sccache]: https://github.com/mozilla/sccache

+## Cargo.toml vs Cargo.lock
+
+`Cargo.toml` and `Cargo.lock` serve two different purposes. Before we talk
+about them, here’s a summary:
+
+* `Cargo.toml` is about describing your dependencies in a broad sense, and is
+ written by you.
+* `Cargo.lock` contains exact information about your dependencies. It is
+ maintained by Cargo and should not be manually edited.
+
+If you’re building a library that other packages will depend on, put
+`Cargo.lock` in your `.gitignore`. If you’re building an executable like a
+command-line tool or an application, check `Cargo.lock` into `git`. If you're
+curious about why that is, see ["Why do binaries have `Cargo.lock` in version
+control, but not libraries?" in the
+FAQ](faq.html#why-do-binaries-have-cargolock-in-version-control-but-not-libraries).
+
+Let’s dig in a little bit more.
+
+`Cargo.toml` is a **manifest** file in which we can specify a bunch of
+different metadata about our package. For example, we can say that we depend
+on another package:
+
+```toml
+[package]
+name = "hello_world"
+version = "0.1.0"
+authors = ["Your Name <you@example.com>"]
+
+[dependencies]
+rand = { git = "https://github.com/rust-lang-nursery/rand.git" }
+```
+
+This package has a single dependency, on the `rand` library. We’ve stated in
+this case that we’re relying on a particular Git repository that lives on
+GitHub. Since we haven’t specified any other information, Cargo assumes that
+we intend to use the latest commit on the `master` branch to build our package.
+
+Sound good? Well, there’s one problem: If you build this package today, and
+then you send a copy to me, and I build this package tomorrow, something bad
+could happen. There could be more commits to `rand` in the meantime, and my
+build would include new commits while yours would not. Therefore, we would
+get different builds. This would be bad because we want reproducible builds.
+
+We could fix this problem by putting a `rev` line in our `Cargo.toml`:
+
+```toml
+[dependencies]
+rand = { git = "https://github.com/rust-lang-nursery/rand.git", rev = "9f35b8e" }
+```
+
+Now our builds will be the same. But there’s a big drawback: now we have to
+manually think about SHA-1s every time we want to update our library. This is
+both tedious and error prone.
+
+Enter the `Cargo.lock`. Because of its existence, we don’t need to manually
+keep track of the exact revisions: Cargo will do it for us. When we have a
+manifest like this:
+
+```toml
+[package]
+name = "hello_world"
+version = "0.1.0"
+authors = ["Your Name <you@example.com>"]
+
+[dependencies]
+rand = { git = "https://github.com/rust-lang-nursery/rand.git" }
+```
+
+Cargo will take the latest commit and write that information out into our
+`Cargo.lock` when we build for the first time. That file will look like this:
+
+```toml
+[[package]]
+name = "hello_world"
+version = "0.1.0"
+dependencies = [
+ "rand 0.1.0 (git+https://github.com/rust-lang-nursery/rand.git#9f35b8e439eeedd60b9414c58f389bdc6a3284f9)",
+]
+
+[[package]]
+name = "rand"
+version = "0.1.0"
+source = "git+https://github.com/rust-lang-nursery/rand.git#9f35b8e439eeedd60b9414c58f389bdc6a3284f9"
+```
+
+You can see that there’s a lot more information here, including the exact
+revision we used to build. Now when you give your package to someone else,
+they’ll use the exact same SHA, even though we didn’t specify it in our
+`Cargo.toml`.
+
+When we’re ready to opt in to a new version of the library, Cargo can
+re-calculate the dependencies and update things for us:
+
+```console
+$ cargo update # updates all dependencies
+$ cargo update -p rand # updates just “rand”
+```
+
+This will write out a new `Cargo.lock` with the new version information. Note
+that the argument to `cargo update` is actually a
+[Package ID Specification](reference/pkgid-spec.html) and `rand` is just a short
+specification.

+## Continuous Integration
+
+### Travis CI
+
+To test your package on Travis CI, here is a sample `.travis.yml` file:
+
+```yaml
+language: rust
+rust:
+ - stable
+ - beta
+ - nightly
+matrix:
+ allow_failures:
+ - rust: nightly
+```
+
+This will test all three release channels, but any breakage in nightly
+will not fail your overall build. Please see the [Travis CI Rust
+documentation](https://docs.travis-ci.com/user/languages/rust/) for more
+information.
+
+### GitLab CI
+
+To test your package on GitLab CI, here is a sample `.gitlab-ci.yml` file:
+
+```yaml
+stages:
+ - build
+
+rust-latest:
+ stage: build
+ image: rust:latest
+ script:
+ - cargo build --verbose
+ - cargo test --verbose
+
+rust-nightly:
+ stage: build
+ image: rustlang/rust:nightly
+ script:
+ - cargo build --verbose
+ - cargo test --verbose
+ allow_failure: true
+```
+
+This will test on the stable channel and nightly channel, but any
+breakage in nightly will not fail your overall build. Please see the
+[GitLab CI](https://docs.gitlab.com/ce/ci/yaml/README.html) for more
+information.
--- /dev/null
+## Creating a New Package
+
+To start a new package with Cargo, use `cargo new`:
+
+```console
+$ cargo new hello_world --bin
+```
+
+We’re passing `--bin` because we’re making a binary program: if we
+were making a library, we’d pass `--lib`. This also initializes a new `git`
+repository by default. If you don't want it to do that, pass `--vcs none`.
+
+Let’s check out what Cargo has generated for us:
+
+```console
+$ cd hello_world
+$ tree .
+.
+├── Cargo.toml
+└── src
+ └── main.rs
+
+1 directory, 2 files
+```
+
+Let’s take a closer look at `Cargo.toml`:
+
+```toml
+[package]
+name = "hello_world"
+version = "0.1.0"
+authors = ["Your Name <you@example.com>"]
+```
+
+This is called a **manifest**, and it contains all of the metadata that Cargo
+needs to compile your package.
+
+Here’s what’s in `src/main.rs`:
+
+```rust
+fn main() {
+ println!("Hello, world!");
+}
+```
+
+Cargo generated a “hello world” for us. Let’s compile it:
+
+```console
+$ cargo build
+ Compiling hello_world v0.1.0 (file:///path/to/package/hello_world)
+```
+
+And then run it:
+
+```console
+$ ./target/debug/hello_world
+Hello, world!
+```
+
+We can also use `cargo run` to compile and then run it, all in one step (You
+won't see the `Compiling` line if you have not made any changes since you last
+compiled):
+
+```console
+$ cargo run
+ Compiling hello_world v0.1.0 (file:///path/to/package/hello_world)
+ Running `target/debug/hello_world`
+Hello, world!
+```
+
+You’ll now notice a new file, `Cargo.lock`. It contains information about our
+dependencies. Since we don’t have any yet, it’s not very interesting.
+
+Once you’re ready for release, you can use `cargo build --release` to compile
+your files with optimizations turned on:
+
+```console
+$ cargo build --release
+ Compiling hello_world v0.1.0 (file:///path/to/package/hello_world)
+```
+
+`cargo build --release` puts the resulting binary in `target/release` instead of
+`target/debug`.
+
+Compiling in debug mode is the default for development-- compilation time is
+shorter since the compiler doesn't do optimizations, but the code will run
+slower. Release mode takes longer to compile, but the code will run faster.
--- /dev/null
+## Dependencies
+
+[crates.io] is the Rust community's central package registry that serves as a
+location to discover and download packages. `cargo` is configured to use it by
+default to find requested packages.
+
+To depend on a library hosted on [crates.io], add it to your `Cargo.toml`.
+
+[crates.io]: https://crates.io/
+
+### Adding a dependency
+
+If your `Cargo.toml` doesn't already have a `[dependencies]` section, add that,
+then list the crate name and version that you would like to use. This example
+adds a dependency of the `time` crate:
+
+```toml
+[dependencies]
+time = "0.1.12"
+```
+
+The version string is a [semver] version requirement. The [specifying
+dependencies](reference/specifying-dependencies.html) docs have more information about
+the options you have here.
+
+[semver]: https://github.com/steveklabnik/semver#requirements
+
+If we also wanted to add a dependency on the `regex` crate, we would not need
+to add `[dependencies]` for each crate listed. Here's what your whole
+`Cargo.toml` file would look like with dependencies on the `time` and `regex`
+crates:
+
+```toml
+[package]
+name = "hello_world"
+version = "0.1.0"
+authors = ["Your Name <you@example.com>"]
+
+[dependencies]
+time = "0.1.12"
+regex = "0.1.41"
+```
+
+Re-run `cargo build`, and Cargo will fetch the new dependencies and all of
+their dependencies, compile them all, and update the `Cargo.lock`:
+
+```console
+$ cargo build
+ Updating crates.io index
+ Downloading memchr v0.1.5
+ Downloading libc v0.1.10
+ Downloading regex-syntax v0.2.1
+ Downloading memchr v0.1.5
+ Downloading aho-corasick v0.3.0
+ Downloading regex v0.1.41
+ Compiling memchr v0.1.5
+ Compiling libc v0.1.10
+ Compiling regex-syntax v0.2.1
+ Compiling memchr v0.1.5
+ Compiling aho-corasick v0.3.0
+ Compiling regex v0.1.41
+ Compiling hello_world v0.1.0 (file:///path/to/package/hello_world)
+```
+
+Our `Cargo.lock` contains the exact information about which revision of all of
+these dependencies we used.
+
+Now, if `regex` gets updated, we will still build with the same revision until
+we choose to `cargo update`.
+
+You can now use the `regex` library using `extern crate` in `main.rs`.
+
+```rust
+extern crate regex;
+
+use regex::Regex;
+
+fn main() {
+ let re = Regex::new(r"^\d{4}-\d{2}-\d{2}$").unwrap();
+ println!("Did our date match? {}", re.is_match("2014-01-01"));
+}
+```
+
+Running it will show:
+
+```console
+$ cargo run
+ Running `target/hello_world`
+Did our date match? true
+```

+## Cargo Guide
+
+This guide will give you all that you need to know about how to use Cargo to
+develop Rust packages.
+
+* [Why Cargo Exists](guide/why-cargo-exists.html)
+* [Creating a New Package](guide/creating-a-new-project.html)
+* [Working on an Existing Cargo Package](guide/working-on-an-existing-project.html)

+* [Build Cache](guide/build-cache.html)
--- /dev/null
+## Package Layout
+
+Cargo uses conventions for file placement to make it easy to dive into a new
+Cargo package:
+
+```
+.
+├── Cargo.lock
+├── Cargo.toml
+├── benches
+│ └── large-input.rs
+├── examples
+│ └── simple.rs
+├── src
+│ ├── bin
+│ │ └── another_executable.rs
+│ ├── lib.rs
+│ └── main.rs
+└── tests
+ └── some-integration-tests.rs
+```
+
+* `Cargo.toml` and `Cargo.lock` are stored in the root of your package (*package
+ root*).
+* Source code goes in the `src` directory.
+* The default library file is `src/lib.rs`.
+* The default executable file is `src/main.rs`.
+* Other executables can be placed in `src/bin/*.rs`.
+* Integration tests go in the `tests` directory (unit tests go in each file
+ they're testing).
+* Examples go in the `examples` directory.
+* Benchmarks go in the `benches` directory.
+
+These are explained in more detail in the [manifest
+description](reference/manifest.html#the-project-layout).
--- /dev/null
+## Tests
+
+Cargo can run your tests with the `cargo test` command. Cargo looks for tests
+to run in two places: in each of your `src` files and any tests in `tests/`.
+Tests in your `src` files should be unit tests, and tests in `tests/` should be
+integration-style tests. As such, you’ll need to import your crates into
+the files in `tests`.
+
+Here's an example of running `cargo test` in our package, which currently has
+no tests:
+
+```console
+$ cargo test
+ Compiling rand v0.1.0 (https://github.com/rust-lang-nursery/rand.git#9f35b8e)
+ Compiling hello_world v0.1.0 (file:///path/to/package/hello_world)
+ Running target/test/hello_world-9c2b65bbb79eabce
+
+running 0 tests
+
+test result: ok. 0 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out
+```
+
+If our package had tests, we would see more output with the correct number of
+tests.
+
+You can also run a specific test by passing a filter:
+
+```console
+$ cargo test foo
+```
+
+This will run any test with `foo` in its name.
+
+`cargo test` runs additional checks as well. For example, it will compile any
+examples you’ve included and will also test the examples in your
+documentation. Please see the [testing guide][testing] in the Rust
+documentation for more details.
+
+[testing]: https://doc.rust-lang.org/book/testing.html
--- /dev/null
+## Why Cargo Exists
+
+Cargo is a tool that allows Rust packages to declare their various
+dependencies and ensure that you’ll always get a repeatable build.
+
+To accomplish this goal, Cargo does four things:
+
+* Introduces two metadata files with various bits of package information.
+* Fetches and builds your package’s dependencies.
+* Invokes `rustc` or another build tool with the correct parameters to build
+ your package.
+* Introduces conventions to make working with Rust packages easier.
--- /dev/null
+## Working on an Existing Cargo Package
+
+If you download an existing package that uses Cargo, it’s really easy
+to get going.
+
+First, get the package from somewhere. In this example, we’ll use `rand`
+cloned from its repository on GitHub:
+
+```console
+$ git clone https://github.com/rust-lang-nursery/rand.git
+$ cd rand
+```
+
+To build, use `cargo build`:
+
+```console
+$ cargo build
+ Compiling rand v0.1.0 (file:///path/to/package/rand)
+```
+
+This will fetch all of the dependencies and then build them, along with the
+package.

+# The Cargo Book
+
+
+
+Cargo is the [Rust] *package manager*. Cargo downloads your Rust package’s
+dependencies, compiles your packages, makes distributable packages, and uploads them to
+[crates.io], the Rust community’s *package registry*. You can contribute
+to this book on [GitHub].

+## Build Scripts
+
+Some packages need to compile third-party non-Rust code, for example C
+libraries. Other packages need to link to C libraries which can either be
+located on the system or possibly need to be built from source. Others still
+need facilities for functionality such as code generation before building (think
+parser generators).
+
+Cargo does not aim to replace other tools that are well-optimized for
+these tasks, but it does integrate with them with the `build` configuration
+option.
+
+```toml
+[package]
+# ...
+build = "build.rs"
+```
+
+The Rust file designated by the `build` command (relative to the package root)
+will be compiled and invoked before anything else is compiled in the package,
+allowing your Rust code to depend on the built or generated artifacts.
+By default Cargo looks up for `"build.rs"` file in a package root (even if you
+do not specify a value for `build`). Use `build = "custom_build_name.rs"` to specify
+a custom build name or `build = false` to disable automatic detection of the build script.
+
+Some example use cases of the build command are:
+
+* Building a bundled C library.
+* Finding a C library on the host system.
+* Generating a Rust module from a specification.
+* Performing any platform-specific configuration needed for the crate.
+
+Each of these use cases will be detailed in full below to give examples of how
+the build command works.
+
+### Inputs to the Build Script
+
+When the build script is run, there are a number of inputs to the build script,
+all passed in the form of [environment variables][env].
+
+In addition to environment variables, the build script’s current directory is
+the source directory of the build script’s package.
+
+[env]: reference/environment-variables.html
+
+### Outputs of the Build Script
+
+All the lines printed to stdout by a build script are written to a file like
+`target/debug/build/<pkg>/output` (the precise location may depend on your
+configuration). If you would like to see such output directly in your terminal,
+invoke cargo as 'very verbose' with the `-vv` flag. Note that if neither the
+build script nor package source files are modified, subsequent calls to
+cargo with `-vv` will **not** print output to the terminal because a
+new build is not executed. Run `cargo clean` before each cargo invocation
+if you want to ensure that output is always displayed on your terminal.
+Any line that starts with `cargo:` is interpreted directly by Cargo.
+This line must be of the form `cargo:key=value`, like the examples below:
+
+```
+# specially recognized by Cargo
+cargo:rustc-link-lib=static=foo
+cargo:rustc-link-search=native=/path/to/foo
+cargo:rustc-cfg=foo
+cargo:rustc-env=FOO=bar
+# arbitrary user-defined metadata
+cargo:root=/path/to/foo
+cargo:libdir=/path/to/foo/lib
+cargo:include=/path/to/foo/include
+```
+
+On the other hand, lines printed to stderr are written to a file like
+`target/debug/build/<pkg>/stderr` but are not interpreted by cargo.
+
+There are a few special keys that Cargo recognizes, some affecting how the
+crate is built:
+
+* `rustc-link-lib=[KIND=]NAME` indicates that the specified value is a library
+ name and should be passed to the compiler as a `-l` flag. The optional `KIND`
+ can be one of `static`, `dylib` (the default), or `framework`, see
+ `rustc --help` for more details.
+* `rustc-link-search=[KIND=]PATH` indicates the specified value is a library
+ search path and should be passed to the compiler as a `-L` flag. The optional
+ `KIND` can be one of `dependency`, `crate`, `native`, `framework` or `all`
+ (the default), see `rustc --help` for more details.
+* `rustc-flags=FLAGS` is a set of flags passed to the compiler, only `-l` and
+ `-L` flags are supported.
+* `rustc-cfg=FEATURE` indicates that the specified feature will be passed as a
+ `--cfg` flag to the compiler. This is often useful for performing compile-time
+ detection of various features.
+* `rustc-env=VAR=VALUE` indicates that the specified environment variable
+ will be added to the environment which the compiler is run within.
+ The value can be then retrieved by the `env!` macro in the compiled crate.
+ This is useful for embedding additional metadata in crate's code,
+ such as the hash of Git HEAD or the unique identifier of a continuous
+ integration server.
+* `rerun-if-changed=PATH` is a path to a file or directory which indicates that
+ the build script should be re-run if it changes (detected by a more-recent
+ last-modified timestamp on the file). Normally build scripts are re-run if
+ any file inside the crate root changes, but this can be used to scope changes
+ to just a small set of files. (If this path points to a directory the entire
+ directory will not be traversed for changes -- only changes to the timestamp
+ of the directory itself (which corresponds to some types of changes within the
+ directory, depending on platform) will trigger a rebuild. To request a re-run
+ on any changes within an entire directory, print a line for the directory and
+ another line for everything inside it, recursively.)
+ Note that if the build script itself (or one of its dependencies) changes,
+ then it's rebuilt and rerun unconditionally, so
+ `cargo:rerun-if-changed=build.rs` is almost always redundant (unless you
+ want to ignore changes in all other files except for `build.rs`).
+* `rerun-if-env-changed=VAR` is the name of an environment variable which
+ indicates that if the environment variable's value changes the build script
+ should be rerun. This basically behaves the same as `rerun-if-changed` except
+ that it works with environment variables instead. Note that the environment
+ variables here are intended for global environment variables like `CC` and
+ such, it's not necessary to use this for env vars like `TARGET` that Cargo
+ sets. Also note that if `rerun-if-env-changed` is printed out then Cargo will
+ *only* rerun the build script if those environment variables change or if
+ files printed out by `rerun-if-changed` change.
+
+* `warning=MESSAGE` is a message that will be printed to the main console after
+ a build script has finished running. Warnings are only shown for path
+ dependencies (that is, those you're working on locally), so for example
+ warnings printed out in crates.io crates are not emitted by default.
+
+Any other element is a user-defined metadata that will be passed to
+dependents. More information about this can be found in the [`links`][links]
+section.
+
+[links]: #the-links-manifest-key
+
+### Build Dependencies
+
+Build scripts are also allowed to have dependencies on other Cargo-based crates.
+Dependencies are declared through the `build-dependencies` section of the
+manifest.
+
+```toml
+[build-dependencies]
+foo = { git = "https://github.com/your-packages/foo" }
+```
+
+The build script **does not** have access to the dependencies listed in the
+`dependencies` or `dev-dependencies` section (they’re not built yet!). All build
+dependencies will also not be available to the package itself unless explicitly
+stated as so.
+
+### The `links` Manifest Key
+
+In addition to the manifest key `build`, Cargo also supports a `links` manifest
+key to declare the name of a native library that is being linked to:
+
+```toml
+[package]
+# ...
+links = "foo"
+build = "build.rs"
+```
+
+This manifest states that the package links to the `libfoo` native library, and
+it also has a build script for locating and/or building the library. Cargo
+requires that a `build` command is specified if a `links` entry is also
+specified.
+
+The purpose of this manifest key is to give Cargo an understanding about the set
+of native dependencies that a package has, as well as providing a principled
+system of passing metadata between package build scripts.
+
+Primarily, Cargo requires that there is at most one package per `links` value.
+In other words, it’s forbidden to have two packages link to the same native
+library. Note, however, that there are [conventions in place][star-sys] to
+alleviate this.
+
+[star-sys]: #a-sys-packages
+
+As mentioned above in the output format, each build script can generate an
+arbitrary set of metadata in the form of key-value pairs. This metadata is
+passed to the build scripts of **dependent** packages. For example, if `libbar`
+depends on `libfoo`, then if `libfoo` generates `key=value` as part of its
+metadata, then the build script of `libbar` will have the environment variables
+`DEP_FOO_KEY=value`.
+
+Note that metadata is only passed to immediate dependents, not transitive
+dependents. The motivation for this metadata passing is outlined in the linking
+to system libraries case study below.
+
+### Overriding Build Scripts
+
+If a manifest contains a `links` key, then Cargo supports overriding the build
+script specified with a custom library. The purpose of this functionality is to
+prevent running the build script in question altogether and instead supply the
+metadata ahead of time.
+
+To override a build script, place the following configuration in any acceptable
+Cargo [configuration location](reference/config.html).
+
+```toml
+[target.x86_64-unknown-linux-gnu.foo]
+rustc-link-search = ["/path/to/foo"]
+rustc-link-lib = ["foo"]
+root = "/path/to/foo"
+key = "value"
+```
+
+This section states that for the target `x86_64-unknown-linux-gnu` the library
+named `foo` has the metadata specified. This metadata is the same as the
+metadata generated as if the build script had run, providing a number of
+key/value pairs where the `rustc-flags`, `rustc-link-search`, and
+`rustc-link-lib` keys are slightly special.
+
+With this configuration, if a package declares that it links to `foo` then the
+build script will **not** be compiled or run, and the metadata specified will
+instead be used.
+
+### Case study: Code generation
+
+Some Cargo packages need to have code generated just before they are compiled
+for various reasons. Here we’ll walk through a simple example which generates a
+library call as part of the build script.
+
+First, let’s take a look at the directory structure of this package:
+
+```
+.
+├── Cargo.toml
+├── build.rs
+└── src
+ └── main.rs
+
+1 directory, 3 files
+```
+
+Here we can see that we have a `build.rs` build script and our binary in
+`main.rs`. Next, let’s take a look at the manifest:
+
+```toml
+# Cargo.toml
+
+[package]
+name = "hello-from-generated-code"
+version = "0.1.0"
+authors = ["you@example.com"]
+build = "build.rs"
+```
+
+Here we can see we’ve got a build script specified which we’ll use to generate
+some code. Let’s see what’s inside the build script:
+
+```rust,no_run
+// build.rs
+
+use std::env;
+use std::fs::File;
+use std::io::Write;
+use std::path::Path;
+
+fn main() {
+ let out_dir = env::var("OUT_DIR").unwrap();
+ let dest_path = Path::new(&out_dir).join("hello.rs");
+ let mut f = File::create(&dest_path).unwrap();
+
+ f.write_all(b"
+ pub fn message() -> &'static str {
+ \"Hello, World!\"
+ }
+ ").unwrap();
+}
+```
+
+There’s a couple of points of note here:
+
+* The script uses the `OUT_DIR` environment variable to discover where the
+ output files should be located. It can use the process’ current working
+ directory to find where the input files should be located, but in this case we
+ don’t have any input files.
+* In general, build scripts should not modify any files outside of `OUT_DIR`.
+ It may seem fine on the first blush, but it does cause problems when you use
+ such crate as a dependency, because there's an *implicit* invariant that
+ sources in `.cargo/registry` should be immutable. `cargo` won't allow such
+ scripts when packaging.
+* This script is relatively simple as it just writes out a small generated file.
+ One could imagine that other more fanciful operations could take place such as
+ generating a Rust module from a C header file or another language definition,
+ for example.
+
+Next, let’s peek at the library itself:
+
+```rust,ignore
+// src/main.rs
+
+include!(concat!(env!("OUT_DIR"), "/hello.rs"));
+
+fn main() {
+ println!("{}", message());
+}
+```
+
+This is where the real magic happens. The library is using the rustc-defined
+`include!` macro in combination with the `concat!` and `env!` macros to include
+the generated file (`hello.rs`) into the crate’s compilation.
+
+Using the structure shown here, crates can include any number of generated files
+from the build script itself.
+
+### Case study: Building some native code
+
+Sometimes it’s necessary to build some native C or C++ code as part of a
+package. This is another excellent use case of leveraging the build script to
+build a native library before the Rust crate itself. As an example, we’ll create
+a Rust library which calls into C to print “Hello, World!”.
+
+Like above, let’s first take a look at the package layout:
+
+```
+.
+├── Cargo.toml
+├── build.rs
+└── src
+ ├── hello.c
+ └── main.rs
+
+1 directory, 4 files
+```
+
+Pretty similar to before! Next, the manifest:
+
+```toml
+# Cargo.toml
+
+[package]
+name = "hello-world-from-c"
+version = "0.1.0"
+authors = ["you@example.com"]
+build = "build.rs"
+```
+
+For now we’re not going to use any build dependencies, so let’s take a look at
+the build script now:
+
+```rust,no_run
+// build.rs
+
+use std::process::Command;
+use std::env;
+use std::path::Path;
+
+fn main() {
+ let out_dir = env::var("OUT_DIR").unwrap();
+
+ // note that there are a number of downsides to this approach, the comments
+ // below detail how to improve the portability of these commands.
+ Command::new("gcc").args(&["src/hello.c", "-c", "-fPIC", "-o"])
+ .arg(&format!("{}/hello.o", out_dir))
+ .status().unwrap();
+ Command::new("ar").args(&["crus", "libhello.a", "hello.o"])
+ .current_dir(&Path::new(&out_dir))
+ .status().unwrap();
+
+ println!("cargo:rustc-link-search=native={}", out_dir);
+ println!("cargo:rustc-link-lib=static=hello");
+}
+```
+
+This build script starts out by compiling our C file into an object file (by
+invoking `gcc`) and then converting this object file into a static library (by
+invoking `ar`). The final step is feedback to Cargo itself to say that our
+output was in `out_dir` and the compiler should link the crate to `libhello.a`
+statically via the `-l static=hello` flag.
+
+Note that there are a number of drawbacks to this hardcoded approach:
+
+* The `gcc` command itself is not portable across platforms. For example it’s
+ unlikely that Windows platforms have `gcc`, and not even all Unix platforms
+ may have `gcc`. The `ar` command is also in a similar situation.
+* These commands do not take cross-compilation into account. If we’re cross
+ compiling for a platform such as Android it’s unlikely that `gcc` will produce
+ an ARM executable.
+
+Not to fear, though, this is where a `build-dependencies` entry would help! The
+Cargo ecosystem has a number of packages to make this sort of task much easier,
+portable, and standardized. For example, the build script could be written as:
+
+```rust,ignore
+// build.rs
+
+// Bring in a dependency on an externally maintained `cc` package which manages
+// invoking the C compiler.
+extern crate cc;
+
+fn main() {
+ cc::Build::new()
+ .file("src/hello.c")
+ .compile("hello");
+}
+```
+
+Add a build time dependency on the `cc` crate with the following addition to
+your `Cargo.toml`:
+
+```toml
+[build-dependencies]
+cc = "1.0"
+```
+
+The [`cc` crate](https://crates.io/crates/cc) abstracts a range of build
+script requirements for C code:
+
+* It invokes the appropriate compiler (MSVC for windows, `gcc` for MinGW, `cc`
+ for Unix platforms, etc.).
+* It takes the `TARGET` variable into account by passing appropriate flags to
+ the compiler being used.
+* Other environment variables, such as `OPT_LEVEL`, `DEBUG`, etc., are all
+ handled automatically.
+* The stdout output and `OUT_DIR` locations are also handled by the `cc`
+ library.
+
+Here we can start to see some of the major benefits of farming as much
+functionality as possible out to common build dependencies rather than
+duplicating logic across all build scripts!
+
+Back to the case study though, let’s take a quick look at the contents of the
+`src` directory:
+
+```c
+// src/hello.c
+
+#include <stdio.h>
+
+void hello() {
+ printf("Hello, World!\n");
+}
+```
+
+```rust,ignore
+// src/main.rs
+
+// Note the lack of the `#[link]` attribute. We’re delegating the responsibility
+// of selecting what to link to over to the build script rather than hardcoding
+// it in the source file.
+extern { fn hello(); }
+
+fn main() {
+ unsafe { hello(); }
+}
+```
+
+And there we go! This should complete our example of building some C code from a
+Cargo package using the build script itself. This also shows why using a build
+dependency can be crucial in many situations and even much more concise!
+
+We’ve also seen a brief example of how a build script can use a crate as a
+dependency purely for the build process and not for the crate itself at runtime.
+
+### Case study: Linking to system libraries
+
+The final case study here will be investigating how a Cargo library links to a
+system library and how the build script is leveraged to support this use case.
+
+Quite frequently a Rust crate wants to link to a native library often provided
+on the system to bind its functionality or just use it as part of an
+implementation detail. This is quite a nuanced problem when it comes to
+performing this in a platform-agnostic fashion, and the purpose of a build
+script is again to farm out as much of this as possible to make this as easy as
+possible for consumers.
+
+As an example to follow, let’s take a look at one of [Cargo’s own
+dependencies][git2-rs], [libgit2][libgit2]. The C library has a number of
+constraints:
+
+[git2-rs]: https://github.com/alexcrichton/git2-rs/tree/master/libgit2-sys
+[libgit2]: https://github.com/libgit2/libgit2
+
+* It has an optional dependency on OpenSSL on Unix to implement the https
+ transport.
+* It has an optional dependency on libssh2 on all platforms to implement the ssh
+ transport.
+* It is often not installed on all systems by default.
+* It can be built from source using `cmake`.
+
+To visualize what’s going on here, let’s take a look at the manifest for the
+relevant Cargo package that links to the native C library.
+
+```toml
+[package]
+name = "libgit2-sys"
+version = "0.1.0"
+authors = ["..."]
+links = "git2"
+build = "build.rs"
+
+[dependencies]
+libssh2-sys = { git = "https://github.com/alexcrichton/ssh2-rs" }
+
+[target.'cfg(unix)'.dependencies]
+openssl-sys = { git = "https://github.com/alexcrichton/openssl-sys" }
+
+# ...
+```
+
+As the above manifests show, we’ve got a `build` script specified, but it’s
+worth noting that this example has a `links` entry which indicates that the
+crate (`libgit2-sys`) links to the `git2` native library.
+
+Here we also see that we chose to have the Rust crate have an unconditional
+dependency on `libssh2` via the `libssh2-sys` crate, as well as a
+platform-specific dependency on `openssl-sys` for \*nix (other variants elided
+for now). It may seem a little counterintuitive to express *C dependencies* in
+the *Cargo manifest*, but this is actually using one of Cargo’s conventions in
+this space.
+
+### `*-sys` Packages
+
+To alleviate linking to system libraries, crates.io has a *convention* of package
+naming and functionality. Any package named `foo-sys` should provide two major
+pieces of functionality:
+
+* The library crate should link to the native library `libfoo`. This will often
+ probe the current system for `libfoo` before resorting to building from
+ source.
+* The library crate should provide **declarations** for functions in `libfoo`,
+ but **not** bindings or higher-level abstractions.
+
+The set of `*-sys` packages provides a common set of dependencies for linking
+to native libraries. There are a number of benefits earned from having this
+convention of native-library-related packages:
+
+* Common dependencies on `foo-sys` alleviates the above rule about one package
+ per value of `links`.
+* A common dependency allows centralizing logic on discovering `libfoo` itself
+ (or building it from source).
+* These dependencies are easily overridable.
+
+### Building libgit2
+
+Now that we’ve got libgit2’s dependencies sorted out, we need to actually write
+the build script. We’re not going to look at specific snippets of code here and
+instead only take a look at the high-level details of the build script of
+`libgit2-sys`. This is not recommending all packages follow this strategy, but
+rather just outlining one specific strategy.
+
+The first step of the build script should do is to query whether libgit2 is
+already installed on the host system. To do this we’ll leverage the preexisting
+tool `pkg-config` (when its available). We’ll also use a `build-dependencies`
+section to refactor out all the `pkg-config` related code (or someone’s already
+done that!).
+
+If `pkg-config` failed to find libgit2, or if `pkg-config` just wasn’t
+installed, the next step is to build libgit2 from bundled source code
+(distributed as part of `libgit2-sys` itself). There are a few nuances when
+doing so that we need to take into account, however:
+
+* The build system of libgit2, `cmake`, needs to be able to find libgit2’s
+ optional dependency of libssh2. We’re sure we’ve already built it (it’s a
+ Cargo dependency), we just need to communicate this information. To do this
+ we leverage the metadata format to communicate information between build
+ scripts. In this example the libssh2 package printed out `cargo:root=...` to
+ tell us where libssh2 is installed at, and we can then pass this along to
+ cmake with the `CMAKE_PREFIX_PATH` environment variable.
+
+* We’ll need to handle some `CFLAGS` values when compiling C code (and tell
+ `cmake` about this). Some flags we may want to pass are `-m64` for 64-bit
+ code, `-m32` for 32-bit code, or `-fPIC` for 64-bit code as well.
+
+* Finally, we’ll invoke `cmake` to place all output into the `OUT_DIR`
+ environment variable, and then we’ll print the necessary metadata to instruct
+ rustc how to link to libgit2.
+
+Most of the functionality of this build script is easily refactorable into
+common dependencies, so our build script isn’t quite as intimidating as this
+descriptions! In reality it’s expected that build scripts are quite succinct by
+farming logic such as above to build dependencies.

+## Configuration
+
+This document will explain how Cargo’s configuration system works, as well as
+available keys or configuration. For configuration of a package through its
+manifest, see the [manifest format](reference/manifest.html).
+
+### Hierarchical structure
+
+
+Cargo allows local configuration for a particular package as well as global
+configuration, like git. Cargo extends this to a hierarchical strategy.
+If, for example, Cargo were invoked in `/projects/foo/bar/baz`, then the
+following configuration files would be probed for and unified in this order:
+
+* `/projects/foo/bar/baz/.cargo/config`
+* `/projects/foo/bar/.cargo/config`
+* `/projects/foo/.cargo/config`
+* `/projects/.cargo/config`
+* `/.cargo/config`
+* `$HOME/.cargo/config`
+
+With this structure, you can specify configuration per-package, and even
+possibly check it into version control. You can also specify personal defaults
+with a configuration file in your home directory.
+
+### Configuration format
+
+All configuration is currently in the [TOML format][toml] (like the manifest),
+with simple key-value pairs inside of sections (tables) which all get merged
+together.
+
+[toml]: https://github.com/toml-lang/toml
+
+### Configuration keys
+
+All of the following keys are optional, and their defaults are listed as their
+value unless otherwise noted.
+
+Key values that specify a tool may be given as an absolute path, a relative path
+or as a pathless tool name. Absolute paths and pathless tool names are used as
+given. Relative paths are resolved relative to the parent directory of the
+`.cargo` directory of the config file that the value resides within.
+
+```toml
+# An array of paths to local repositories which are to be used as overrides for
+# dependencies. For more information see the Specifying Dependencies guide.

+
+### Environment variables
+
+Cargo can also be configured through environment variables in addition to the
+TOML syntax above. For each configuration key above of the form `foo.bar` the
+environment variable `CARGO_FOO_BAR` can also be used to define the value. For
+example the `build.jobs` key can also be defined by `CARGO_BUILD_JOBS`.
+
+Environment variables will take precedent over TOML configuration, and currently
+only integer, boolean, and string keys are supported to be defined by
+environment variables. This means that [source replacement][source], which is expressed by
+tables, cannot be configured through environment variables.
+
+In addition to the system above, Cargo recognizes a few other specific
+[environment variables][env].
+
+[env]: reference/environment-variables.html
+[source]: reference/source-replacement.html
--- /dev/null
+## Environment Variables
+
+Cargo sets and reads a number of environment variables which your code can detect
+or override. Here is a list of the variables Cargo sets, organized by when it interacts
+with them:
+
+### Environment variables Cargo reads
+
+You can override these environment variables to change Cargo's behavior on your
+system:
+
+* `CARGO_HOME` — Cargo maintains a local cache of the registry index and of git
+ checkouts of crates. By default these are stored under `$HOME/.cargo`, but
+ this variable overrides the location of this directory. Once a crate is cached
+ it is not removed by the clean command.
+* `CARGO_TARGET_DIR` — Location of where to place all generated artifacts,
+ relative to the current working directory.
+* `RUSTC` — Instead of running `rustc`, Cargo will execute this specified
+ compiler instead.
+* `RUSTC_WRAPPER` — Instead of simply running `rustc`, Cargo will execute this
+ specified wrapper instead, passing as its commandline arguments the rustc
+ invocation, with the first argument being rustc.
+* `RUSTDOC` — Instead of running `rustdoc`, Cargo will execute this specified
+ `rustdoc` instance instead.
+* `RUSTDOCFLAGS` — A space-separated list of custom flags to pass to all `rustdoc`
+ invocations that Cargo performs. In contrast with `cargo rustdoc`, this is
+ useful for passing a flag to *all* `rustdoc` instances.
+* `RUSTFLAGS` — A space-separated list of custom flags to pass to all compiler
+ invocations that Cargo performs. In contrast with `cargo rustc`, this is
+ useful for passing a flag to *all* compiler instances.
+* `CARGO_INCREMENTAL` — If this is set to 1 then Cargo will force incremental
+ compilation to be enabled for the current compilation, and when set to 0 it
+ will force disabling it. If this env var isn't present then cargo's defaults
+ will otherwise be used.
+* `CARGO_CACHE_RUSTC_INFO` — If this is set to 0 then Cargo will not try to cache
+ compiler version information.
+
+Note that Cargo will also read environment variables for `.cargo/config`
+configuration values, as described in [that documentation][config-env]
+
+[config-env]: reference/config.html#environment-variables
+
+### Environment variables Cargo sets for crates
+
+Cargo exposes these environment variables to your crate when it is compiled.
+Note that this applies for test binaries as well.
+To get the value of any of these variables in a Rust program, do this:
+
+```rust
+let version = env!("CARGO_PKG_VERSION");
+```
+
+`version` will now contain the value of `CARGO_PKG_VERSION`.
+
+* `CARGO` - Path to the `cargo` binary performing the build.
+* `CARGO_MANIFEST_DIR` - The directory containing the manifest of your package.
+* `CARGO_PKG_VERSION` - The full version of your package.
+* `CARGO_PKG_VERSION_MAJOR` - The major version of your package.
+* `CARGO_PKG_VERSION_MINOR` - The minor version of your package.
+* `CARGO_PKG_VERSION_PATCH` - The patch version of your package.
+* `CARGO_PKG_VERSION_PRE` - The pre-release version of your package.
+* `CARGO_PKG_AUTHORS` - Colon separated list of authors from the manifest of your package.
+* `CARGO_PKG_NAME` - The name of your package.
+* `CARGO_PKG_DESCRIPTION` - The description from the manifest of your package.
+* `CARGO_PKG_HOMEPAGE` - The home page from the manifest of your package.
+* `CARGO_PKG_REPOSITORY` - The repository from the manifest of your package.
+* `OUT_DIR` - If the package has a build script, this is set to the folder where the build
+ script should place its output. See below for more information.
+
+### Environment variables Cargo sets for build scripts
+
+Cargo sets several environment variables when build scripts are run. Because these variables
+are not yet set when the build script is compiled, the above example using `env!` won't work
+and instead you'll need to retrieve the values when the build script is run:
+
+```rust
+use std::env;
+let out_dir = env::var("OUT_DIR").unwrap();
+```
+
+`out_dir` will now contain the value of `OUT_DIR`.
+
+* `CARGO` - Path to the `cargo` binary performing the build.
+* `CARGO_MANIFEST_DIR` - The directory containing the manifest for the package
+ being built (the package containing the build
+ script). Also note that this is the value of the
+ current working directory of the build script when it
+ starts.
+* `CARGO_MANIFEST_LINKS` - the manifest `links` value.
+* `CARGO_FEATURE_<name>` - For each activated feature of the package being
+ built, this environment variable will be present
+ where `<name>` is the name of the feature uppercased
+ and having `-` translated to `_`.
+* `CARGO_CFG_<cfg>` - For each [configuration option][configuration] of the
+ package being built, this environment variable will
+ contain the value of the configuration, where `<cfg>` is
+ the name of the configuration uppercased and having `-`
+ translated to `_`.
+ Boolean configurations are present if they are set, and
+ not present otherwise.
+ Configurations with multiple values are joined to a
+ single variable with the values delimited by `,`.
+* `OUT_DIR` - the folder in which all output should be placed. This folder is
+ inside the build directory for the package being built, and it is
+ unique for the package in question.
+* `TARGET` - the target triple that is being compiled for. Native code should be
+ compiled for this triple. Some more information about target
+ triples can be found in [clang’s own documentation][clang].
+* `HOST` - the host triple of the rust compiler.
+* `NUM_JOBS` - the parallelism specified as the top-level parallelism. This can
+ be useful to pass a `-j` parameter to a system like `make`. Note
+ that care should be taken when interpreting this environment
+ variable. For historical purposes this is still provided but
+ recent versions of Cargo, for example, do not need to run `make
+ -j` as it'll automatically happen. Cargo implements its own
+ [jobserver] and will allow build scripts to inherit this
+ information, so programs compatible with GNU make jobservers will
+ already have appropriately configured parallelism.
+* `OPT_LEVEL`, `DEBUG` - values of the corresponding variables for the
+ profile currently being built.
+* `PROFILE` - `release` for release builds, `debug` for other builds.
+* `DEP_<name>_<key>` - For more information about this set of environment
+ variables, see build script documentation about [`links`][links].
+* `RUSTC`, `RUSTDOC` - the compiler and documentation generator that Cargo has
+ resolved to use, passed to the build script so it might
+ use it as well.
+* `RUSTC_LINKER` - The path to the linker binary that Cargo has resolved to use
+ for the current target, if specified. The linker can be
+ changed by editing `.cargo/config`; see the documentation
+ about [cargo configuration][cargo-config] for more
+ information.

+
+### Environment variables Cargo sets for 3rd party subcommands
+
+Cargo exposes this environment variable to 3rd party subcommands
+(ie. programs named `cargo-foobar` placed in `$PATH`):
+
+* `CARGO` - Path to the `cargo` binary performing the build.
--- /dev/null
+## External tools
+
+One of the goals of Cargo is simple integration with third-party tools, like
+IDEs and other build systems. To make integration easier, Cargo has several
+facilities:
+
+* a `cargo metadata` command, which outputs package structure and dependencies
+ information in JSON,
+
+* a `--message-format` flag, which outputs information about a particular build,
+ and
+
+* support for custom subcommands.
+
+
+### Information about package structure
+
+You can use `cargo metadata` command to get information about package structure
+and dependencies. The output of the command looks like this:
+
+```text
+{
+ // Integer version number of the format.
+ "version": integer,
+
+ // List of packages for this workspace, including dependencies.
+ "packages": [
+ {
+ // Opaque package identifier.
+ "id": PackageId,
+
+ "name": string,
+
+ "version": string,
+
+ "source": SourceId,
+
+ // A list of declared dependencies, see `resolve` field for actual dependencies.
+ "dependencies": [ Dependency ],
+
+ "targets: [ Target ],
+
+ // Path to Cargo.toml
+ "manifest_path": string,
+ }
+ ],
+
+ "workspace_members": [ PackageId ],
+
+ // Dependencies graph.
+ "resolve": {
+ "nodes": [
+ {
+ "id": PackageId,
+ "dependencies": [ PackageId ]
+ }
+ ]
+ }
+}
+```
+
+The format is stable and versioned. When calling `cargo metadata`, you should
+pass `--format-version` flag explicitly to avoid forward incompatibility
+hazard.
+
+If you are using Rust, there is [cargo_metadata] crate.

+
+
+### Information about build
+
+When passing `--message-format=json`, Cargo will output the following
+information during the build:
+
+* compiler errors and warnings,
+
+* produced artifacts,
+
+* results of the build scripts (for example, native dependencies).
+
+The output goes to stdout in the JSON object per line format. The `reason` field
+distinguishes different kinds of messages.
+
+Information about dependencies in the Makefile-compatible format is stored in
+the `.d` files alongside the artifacts.
+
+
+### Custom subcommands
+
+Cargo is designed to be extensible with new subcommands without having to modify
+Cargo itself. This is achieved by translating a cargo invocation of the form
+cargo `(?<command>[^ ]+)` into an invocation of an external tool
+`cargo-${command}`. The external tool must be present in one of the user's
+`$PATH` directories.
+
+When Cargo invokes a custom subcommand, the first argument to the subcommand
+will be the filename of the custom subcommand, as usual. The second argument
+will be the subcommand name itself. For example, the second argument would be
+`${command}` when invoking `cargo-${command}`. Any additional arguments on the
+command line will be forwarded unchanged.
+
+Cargo can also display the help output of a custom subcommand with `cargo help
+${command}`. Cargo assumes that the subcommand will print a help message if its
+third argument is `--help`. So, `cargo help ${command}` would invoke
+`cargo-${command} ${command} --help`.
+
+Custom subcommands may use the `CARGO` environment variable to call back to
+Cargo. Alternatively, it can link to `cargo` crate as a library, but this
+approach has drawbacks:
+
+* Cargo as a library is unstable: the API may change without deprecation
+
+* versions of the linked Cargo library may be different from the Cargo binary

--- /dev/null
+## The Manifest Format
+
+The `Cargo.toml` file for each package is called its *manifest*. Every manifest
+file consists of one or more sections.
+
+### The `[package]` section
+
+The first section in a `Cargo.toml` is `[package]`.
+
+```toml
+[package]
+name = "hello_world" # the name of the package
+version = "0.1.0" # the current version, obeying semver
+authors = ["Alice <a@example.com>", "Bob <b@example.com>"]
+```
+
+All three of these fields are mandatory.
+
+#### The `version` field
+
+Cargo bakes in the concept of [Semantic
+Versioning](http://semver.org/), so make sure you follow some basic rules:
+
+* Before you reach 1.0.0, anything goes, but if you make breaking changes,
+ increment the minor version. In Rust, breaking changes include adding fields to
+ structs or variants to enums.
+* After 1.0.0, only make breaking changes when you increment the major version.
+ Don’t break the build.
+* After 1.0.0, don’t add any new public API (no new `pub` anything) in patch-level
+ versions. Always increment the minor version if you add any new `pub` structs,
+ traits, fields, types, functions, methods or anything else.
+* Use version numbers with three numeric parts such as 1.0.0 rather than 1.0.
+
+#### The `edition` field (optional)
+
+You can opt in to a specific Rust Edition for your package with the
+`edition` key in `Cargo.toml`. If you don't specify the edition, it will
+default to 2015.
+
+```toml
+[package]
+# ...
+edition = '2018'
+```
+
+The `edition` key affects which edition your package is compiled with. Cargo
+will always generate packages via `cargo new` with the `edition` key set to the
+latest edition. Setting the `edition` key in `[package]` will affect all
+targets/crates in the package, including test suites, benchmarks, binaries,
+examples, etc.
+
+#### The `build` field (optional)
+
+This field specifies a file in the package root which is a [build script][1] for
+building native code. More information can be found in the build script
+[guide][1].
+
+[1]: reference/build-scripts.html
+
+```toml
+[package]
+# ...
+build = "build.rs"
+```
+
+#### The `links` field (optional)
+
+This field specifies the name of a native library that is being linked to.
+More information can be found in the [`links`][links] section of the build
+script guide.
+
+[links]: reference/build-scripts.html#the-links-manifest-key
+
+```toml
+[package]
+# ...
+links = "foo"
+build = "build.rs"
+```
+
+#### The `documentation` field (optional)
+
+This field specifies a URL to a website hosting the crate's documentation.
+If no URL is specified in the manifest file, [crates.io][cratesio] will
+automatically link your crate to the corresponding [docs.rs][docsrs] page.
+
+Documentation links from specific hosts are blacklisted. Hosts are added
+to the blacklist if they are known to not be hosting documentation and are
+possibly of malicious intent e.g. ad tracking networks. URLs from the
+following hosts are blacklisted:
+
+* rust-ci.org
+
+Documentation URLs from blacklisted hosts will not appear on crates.io, and
+may be replaced by docs.rs links.
+
+[docsrs]: https://docs.rs/
+[cratesio]: https://crates.io/
+
+#### The `exclude` and `include` fields (optional)
+
+You can explicitly specify to Cargo that a set of [globs][globs] should be
+ignored or included for the purposes of packaging and rebuilding a package. The
+globs specified in the `exclude` field identify a set of files that are not
+included when a package is published as well as ignored for the purposes of
+detecting when to rebuild a package, and the globs in `include` specify files
+that are explicitly included.
+
+If a VCS is being used for a package, the `exclude` field will be seeded with
+the VCS’ ignore settings (`.gitignore` for git for example).
+
+```toml
+[package]
+# ...
+exclude = ["build/**/*.o", "doc/**/*.html"]
+```
+
+```toml
+[package]
+# ...
+include = ["src/**/*", "Cargo.toml"]
+```
+
+The options are mutually exclusive: setting `include` will override an
+`exclude`. Note that `include` must be an exhaustive list of files as otherwise
+necessary source files may not be included.
+
+[globs]: http://doc.rust-lang.org/glob/glob/struct.Pattern.html
+
+#### Migrating to `gitignore`-like pattern matching
+
+The current interpretation of these configs is based on UNIX Globs, as
+implemented in the [`glob` crate](https://crates.io/crates/glob). We want
+Cargo's `include` and `exclude` configs to work as similar to `gitignore` as
+possible. [The `gitignore` specification](https://git-scm.com/docs/gitignore) is
+also based on Globs, but has a bunch of additional features that enable easier
+pattern writing and more control. Therefore, we are migrating the interpretation
+for the rules of these configs to use the [`ignore`
+crate](https://crates.io/crates/ignore), and treat them each rule as a single
+line in a `gitignore` file. See [the tracking
+issue](https://github.com/rust-lang/cargo/issues/4268) for more details on the
+migration.
+
+#### The `publish` field (optional)
+
+The `publish` field can be used to prevent a package from being published to a
+package registry (like *crates.io*) by mistake.
+
+```toml
+[package]
+# ...
+publish = false
+```
+
+#### The `workspace` field (optional)
+
+The `workspace` field can be used to configure the workspace that this package
+will be a member of. If not specified this will be inferred as the first
+Cargo.toml with `[workspace]` upwards in the filesystem.
+
+```toml
+[package]
+# ...
+workspace = "path/to/workspace/root"
+```
+
+For more information, see the documentation for the workspace table below.
+
+#### Package metadata
+
+There are a number of optional metadata fields also accepted under the
+`[package]` section:
+
+```toml
+[package]
+# ...
+
+# A short blurb about the package. This is not rendered in any format when
+# uploaded to crates.io (aka this is not markdown).
+description = "..."
+
+# These URLs point to more information about the package. These are
+# intended to be webviews of the relevant data, not necessarily compatible
+# with VCS tools and the like.
+documentation = "..."
+homepage = "..."
+repository = "..."
+
+# This points to a file under the package root (relative to this `Cargo.toml`).
+# The contents of this file are stored and indexed in the registry.
+# crates.io will render this file and place the result on the crate's page.
+readme = "..."
+
+# This is a list of up to five keywords that describe this crate. Keywords
+# are searchable on crates.io, and you may choose any words that would
+# help someone find this crate.
+keywords = ["...", "..."]
+
+# This is a list of up to five categories where this crate would fit.
+# Categories are a fixed list available at crates.io/category_slugs, and
+# they must match exactly.
+categories = ["...", "..."]
+
+# This is an SPDX 2.1 license expression for this package. Currently
+# crates.io will validate the license provided against a whitelist of
+# known license and exception identifiers from the SPDX license list
+# 2.4. Parentheses are not currently supported.
+#
+# Multiple licenses can be separated with a `/`, although that usage
+# is deprecated. Instead, use a license expression with AND and OR
+# operators to get more explicit semantics.
+license = "..."
+
+# If a package is using a nonstandard license, then this key may be specified in
+# lieu of the above key and must point to a file relative to this manifest
+# (similar to the readme key).
+license-file = "..."
+
+# Optional specification of badges to be displayed on crates.io.
+#
+# - The badges pertaining to build status that are currently available are
+# Appveyor, CircleCI, GitLab, and TravisCI.
+# - Available badges pertaining to code test coverage are Codecov and
+# Coveralls.
+# - There are also maintenance-related badges based on isitmaintained.com
+# which state the issue resolution time, percent of open issues, and future
+# maintenance intentions.
+#
+# If a `repository` key is required, this refers to a repository in
+# `user/repo` format.
+[badges]
+
+# Appveyor: `repository` is required. `branch` is optional; default is `master`
+# `service` is optional; valid values are `github` (default), `bitbucket`, and
+# `gitlab`; `id` is optional; you can specify the appveyor project id if you
+# want to use that instead. `project_name` is optional; use when the repository
+# name differs from the appveyor project name.
+appveyor = { repository = "...", branch = "master", service = "github" }
+
+# Circle CI: `repository` is required. `branch` is optional; default is `master`
+circle-ci = { repository = "...", branch = "master" }
+
+# GitLab: `repository` is required. `branch` is optional; default is `master`
+gitlab = { repository = "...", branch = "master" }
+
+# Travis CI: `repository` in format "<user>/<project>" is required.
+# `branch` is optional; default is `master`
+travis-ci = { repository = "...", branch = "master" }
+
+# Codecov: `repository` is required. `branch` is optional; default is `master`
+# `service` is optional; valid values are `github` (default), `bitbucket`, and
+# `gitlab`.
+codecov = { repository = "...", branch = "master", service = "github" }
+
+# Coveralls: `repository` is required. `branch` is optional; default is `master`
+# `service` is optional; valid values are `github` (default) and `bitbucket`.
+coveralls = { repository = "...", branch = "master", service = "github" }
+
+# Is it maintained resolution time: `repository` is required.
+is-it-maintained-issue-resolution = { repository = "..." }
+
+# Is it maintained percentage of open issues: `repository` is required.
+is-it-maintained-open-issues = { repository = "..." }
+
+# Maintenance: `status` is required. Available options are `actively-developed`,
+# `passively-maintained`, `as-is`, `experimental`, `looking-for-maintainer`,
+# `deprecated`, and the default `none`, which displays no badge on crates.io.
+maintenance = { status = "..." }
+```
+
+The [crates.io](https://crates.io) registry will render the description, display
+the license, link to the three URLs and categorize by the keywords. These keys
+provide useful information to users of the registry and also influence the
+search ranking of a crate. It is highly discouraged to omit everything in a
+published crate.
+
+SPDX 2.1 license expressions are documented
+[here][spdx-2.1-license-expressions]. The current version of the
+license list is available [here][spdx-license-list], and version 2.4
+is available [here][spdx-license-list-2.4].
+
+#### The `metadata` table (optional)
+
+Cargo by default will warn about unused keys in `Cargo.toml` to assist in
+detecting typos and such. The `package.metadata` table, however, is completely
+ignored by Cargo and will not be warned about. This section can be used for
+tools which would like to store package configuration in `Cargo.toml`. For
+example:
+
+```toml
+[package]
+name = "..."
+# ...
+
+# Metadata used when generating an Android APK, for example.
+[package.metadata.android]
+package-name = "my-awesome-android-app"
+assets = "path/to/static"
+```
+
+### Dependency sections
+
+See the [specifying dependencies page](reference/specifying-dependencies.html) for
+information on the `[dependencies]`, `[dev-dependencies]`,
+`[build-dependencies]`, and target-specific `[target.*.dependencies]` sections.
+
+### The `[profile.*]` sections
+
+Cargo supports custom configuration of how rustc is invoked through profiles at
+the top level. Any manifest may declare a profile, but only the top level
+package’s profiles are actually read. All dependencies’ profiles will be
+overridden. This is done so the top-level package has control over how its
+dependencies are compiled.
+
+There are four currently supported profile names, all of which have the same
+configuration available to them. Listed below is the configuration available,
+along with the defaults for each profile.
+
+```toml
+# The development profile, used for `cargo build`.
+[profile.dev]
+opt-level = 0 # controls the `--opt-level` the compiler builds with.
+ # 0-1 is good for debugging. 2 is well-optimized. Max is 3.
+ # 's' attempts to reduce size, 'z' reduces size even more.
+debug = true # (u32 or bool) Include debug information (debug symbols).
+ # Equivalent to `-C debuginfo=2` compiler flag.
+rpath = false # controls whether compiler should set loader paths.
+ # If true, passes `-C rpath` flag to the compiler.
+lto = false # Link Time Optimization usually reduces size of binaries
+ # and static libraries. Increases compilation time.
+ # If true, passes `-C lto` flag to the compiler, and if a
+ # string is specified like 'thin' then `-C lto=thin` will
+ # be passed.
+debug-assertions = true # controls whether debug assertions are enabled
+ # (e.g. debug_assert!() and arithmetic overflow checks)
+codegen-units = 16 # if > 1 enables parallel code generation which improves
+ # compile times, but prevents some optimizations.
+ # Passes `-C codegen-units`.
+panic = 'unwind' # panic strategy (`-C panic=...`), can also be 'abort'
+incremental = true # whether or not incremental compilation is enabled
+overflow-checks = true # use overflow checks for integer arithmetic.
+ # Passes the `-C overflow-checks=...` flag to the compiler.
+
+# The release profile, used for `cargo build --release`.
+[profile.release]
+opt-level = 3
+debug = false
+rpath = false
+lto = false
+debug-assertions = false
+codegen-units = 16
+panic = 'unwind'
+incremental = false
+overflow-checks = false
+
+# The testing profile, used for `cargo test`.
+[profile.test]
+opt-level = 0
+debug = 2
+rpath = false
+lto = false
+debug-assertions = true
+codegen-units = 16
+panic = 'unwind'
+incremental = true
+overflow-checks = true
+
+# The benchmarking profile, used for `cargo bench` and `cargo test --release`.
+[profile.bench]
+opt-level = 3
+debug = false
+rpath = false
+lto = false
+debug-assertions = false
+codegen-units = 16
+panic = 'unwind'
+incremental = false
+overflow-checks = false
+```
+
+### The `[features]` section
+
+Cargo supports features to allow expression of:
+
+* conditional compilation options (usable through `cfg` attributes);
+* optional dependencies, which enhance a package, but are not required; and
+* clusters of optional dependencies, such as `postgres`, that would include the
+ `postgres` package, the `postgres-macros` package, and possibly other packages
+ (such as development-time mocking libraries, debugging tools, etc.).
+
+A feature of a package is either an optional dependency, or a set of other
+features. The format for specifying features is:
+
+```toml
+[package]
+name = "awesome"
+
+[features]
+# The default set of optional packages. Most people will want to use these
+# packages, but they are strictly optional. Note that `session` is not a package
+# but rather another feature listed in this manifest.
+default = ["jquery", "uglifier", "session"]
+
+# A feature with no dependencies is used mainly for conditional compilation,
+# like `#[cfg(feature = "go-faster")]`.
+go-faster = []
+
+# The `secure-password` feature depends on the bcrypt package. This aliasing
+# will allow people to talk about the feature in a higher-level way and allow
+# this package to add more requirements to the feature in the future.
+secure-password = ["bcrypt"]
+
+# Features can be used to reexport features of other packages. The `session`
+# feature of package `awesome` will ensure that the `session` feature of the
+# package `cookie` is also enabled.
+session = ["cookie/session"]
+
+[dependencies]
+# These packages are mandatory and form the core of this package’s distribution.
+cookie = "1.2.0"
+oauth = "1.1.0"
+route-recognizer = "=2.1.0"
+
+# A list of all of the optional dependencies, some of which are included in the
+# above `features`. They can be opted into by apps.
+jquery = { version = "1.0.2", optional = true }
+uglifier = { version = "1.5.3", optional = true }
+bcrypt = { version = "*", optional = true }
+civet = { version = "*", optional = true }
+```
+
+To use the package `awesome`:
+
+```toml
+[dependencies.awesome]
+version = "1.3.5"
+default-features = false # do not include the default features, and optionally
+ # cherry-pick individual features
+features = ["secure-password", "civet"]
+```
+
+#### Rules
+
+The usage of features is subject to a few rules:
+
+* Feature names must not conflict with other package names in the manifest. This
+ is because they are opted into via `features = [...]`, which only has a single
+ namespace.
+* With the exception of the `default` feature, all features are opt-in. To opt
+ out of the default feature, use `default-features = false` and cherry-pick
+ individual features.
+* Feature groups are not allowed to cyclically depend on one another.
+* Dev-dependencies cannot be optional.
+* Features groups can only reference optional dependencies.
+* When a feature is selected, Cargo will call `rustc` with `--cfg
+ feature="${feature_name}"`. If a feature group is included, it and all of its
+ individual features will be included. This can be tested in code via
+ `#[cfg(feature = "foo")]`.
+
+Note that it is explicitly allowed for features to not actually activate any
+optional dependencies. This allows packages to internally enable/disable
+features without requiring a new dependency.
+
+#### Usage in end products
+
+One major use-case for this feature is specifying optional features in
+end-products. For example, the Servo package may want to include optional
+features that people can enable or disable when they build it.
+
+In that case, Servo will describe features in its `Cargo.toml` and they can be
+enabled using command-line flags:
+
+```console
+$ cargo build --release --features "shumway pdf"
+```
+
+Default features could be excluded using `--no-default-features`.
+
+#### Usage in packages
+
+In most cases, the concept of *optional dependency* in a library is best
+expressed as a separate package that the top-level application depends on.
+
+However, high-level packages, like Iron or Piston, may want the ability to
+curate a number of packages for easy installation. The current Cargo system
+allows them to curate a number of mandatory dependencies into a single package
+for easy installation.
+
+In some cases, packages may want to provide additional curation for optional
+dependencies:
+
+* grouping a number of low-level optional dependencies together into a single
+ high-level feature;
+* specifying packages that are recommended (or suggested) to be included by
+ users of the package; and
+* including a feature (like `secure-password` in the motivating example) that
+ will only work if an optional dependency is available, and would be difficult
+ to implement as a separate package (for example, it may be overly difficult to
+ design an IO package to be completely decoupled from OpenSSL, with opt-in via
+ the inclusion of a separate package).
+
+In almost all cases, it is an antipattern to use these features outside of
+high-level packages that are designed for curation. If a feature is optional, it
+can almost certainly be expressed as a separate package.
+
+### The `[workspace]` section
+
+Packages can define a workspace which is a set of crates that will all share the
+same `Cargo.lock` and output directory. The `[workspace]` table can be defined
+as:
+
+```toml
+[workspace]
+
+# Optional key, inferred from path dependencies if not present.
+# Additional non-path dependencies that should be included must be given here.
+# In particular, for a virtual manifest, all members have to be listed.
+members = ["path/to/member1", "path/to/member2", "path/to/member3/*"]
+
+# Optional key, empty if not present.
+exclude = ["path1", "path/to/dir2"]
+```
+
+Workspaces were added to Cargo as part of [RFC 1525] and have a number of
+properties:
+
+* A workspace can contain multiple crates where one of them is the *root crate*.
+* The *root crate*'s `Cargo.toml` contains the `[workspace]` table, but is not
+ required to have other configuration.
+* Whenever any crate in the workspace is compiled, output is placed in the
+ *workspace root*. i.e. next to the *root crate*'s `Cargo.toml`.
+* The lock file for all crates in the workspace resides in the *workspace root*.
+* The `[patch]`, `[replace]` and `[profile.*]` sections in `Cargo.toml`
+ are only recognized
+ in the *root crate*'s manifest, and ignored in member crates' manifests.
+
+[RFC 1525]: https://github.com/rust-lang/rfcs/blob/master/text/1525-cargo-workspace.md
+
+The *root crate* of a workspace, indicated by the presence of `[workspace]` in
+its manifest, is responsible for defining the entire workspace. All `path`
+dependencies residing in the workspace directory become members. You can add
+additional packages to the workspace by listing them in the `members` key. Note
+that members of the workspaces listed explicitly will also have their path
+dependencies included in the workspace. Sometimes a package may have a lot of
+workspace members and it can be onerous to keep up to date. The path dependency
+can also use [globs][globs] to match multiple paths. Finally, the `exclude`
+key can be used to blacklist paths from being included in a workspace. This can
+be useful if some path dependencies aren't desired to be in the workspace at
+all.
+
+The `package.workspace` manifest key (described above) is used in member crates
+to point at a workspace's root crate. If this key is omitted then it is inferred
+to be the first crate whose manifest contains `[workspace]` upwards in the
+filesystem.
+
+A crate may either specify `package.workspace` or specify `[workspace]`. That
+is, a crate cannot both be a root crate in a workspace (contain `[workspace]`)
+and also be a member crate of another workspace (contain `package.workspace`).
+
+Most of the time workspaces will not need to be dealt with as `cargo new` and
+`cargo init` will handle workspace configuration automatically.
+
+#### Virtual Manifest
+
+In workspace manifests, if the `package` table is present, the workspace root
+crate will be treated as a normal package, as well as a workspace. If the
+`package` table is not present in a workspace manifest, it is called a *virtual
+manifest*.
+
+#### Package selection
+
+In a workspace, package-related cargo commands like `cargo build` apply to
+packages selected by `-p` / `--package` or `--all` command-line parameters.
+When neither is specified, the optional `default-members` configuration is used:
+
+```toml
+[workspace]
+members = ["path/to/member1", "path/to/member2", "path/to/member3/*"]
+default-members = ["path/to/member2", "path/to/member3/foo"]
+```
+
+When specified, `default-members` must expand to a subset of `members`.
+
+When `default-members` is not specified, the default is the root manifest
+if it is a package, or every member manifest (as if `--all` were specified
+on the command-line) for virtual workspaces.
+
+### The project layout
+
+If your package is an executable, name the main source file `src/main.rs`. If it
+is a library, name the main source file `src/lib.rs`.
+
+Cargo will also treat any files located in `src/bin/*.rs` as executables. If your
+executable consists of more than just one source file, you might also use a directory
+inside `src/bin` containing a `main.rs` file which will be treated as an executable
+with a name of the parent directory.
+Do note, however, once you add a `[[bin]]` section ([see
+below](#configuring-a-target)), Cargo will no longer automatically build files
+located in `src/bin/*.rs`. Instead you must create a `[[bin]]` section for
+each file you want to build.
+
+Your package can optionally contain folders named `examples`, `tests`, and
+`benches`, which Cargo will treat as containing examples,
+integration tests, and benchmarks respectively. Analogous to `bin` targets, they
+may be composed of single files or directories with a `main.rs` file.

+
+To structure your code after you've created the files and folders for your
+package, you should remember to use Rust's module system, which you can read
+about in [the book](https://doc.rust-lang.org/book/crates-and-modules.html).
+
+### Examples
+
+Files located under `examples` are example uses of the functionality provided by
+the library. When compiled, they are placed in the `target/examples` directory.
+
+They can compile either as executables (with a `main()` function) or libraries
+and pull in the library by using `extern crate <library-name>`. They are
+compiled when you run your tests to protect them from bitrotting.
+
+You can run individual executable examples with the command `cargo run --example
+<example-name>`.
+
+Specify `crate-type` to make an example be compiled as a library (additional
+information about crate types is available in
+[The Rust Reference](https://doc.rust-lang.org/reference/linkage.html)):
+
+```toml
+[[example]]
+name = "foo"
+crate-type = ["staticlib"]
+```
+
+You can build individual library examples with the command `cargo build
+--example <example-name>`.
+
+### Tests
+
+When you run `cargo test`, Cargo will:
+
+* compile and run your library’s unit tests, which are in the files reachable
+ from `lib.rs` (naturally, any sections marked with `#[cfg(test)]` will be
+ considered at this stage);
+* compile and run your library’s documentation tests, which are embedded inside
+ of documentation blocks;
+* compile and run your library’s [integration tests](#integration-tests); and
+* compile your library’s examples.
+
+#### Integration tests
+
+Each file in `tests/*.rs` is an integration test. When you run `cargo test`,
+Cargo will compile each of these files as a separate crate. The crate can link
+to your library by using `extern crate <library-name>`, like any other code that
+depends on it.
+
+Cargo will not automatically compile files inside subdirectories of `tests`, but
+an integration test can import modules from these directories as usual. For
+example, if you want several integration tests to share some code, you can put
+the shared code in `tests/common/mod.rs` and then put `mod common;` in each of
+the test files.
+
+### Configuring a target
+
+All of the `[[bin]]`, `[lib]`, `[[bench]]`, `[[test]]`, and `[[example]]`
+sections support similar configuration for specifying how a target should be
+built. The double-bracket sections like `[[bin]]` are array-of-table of
+[TOML](https://github.com/toml-lang/toml#array-of-tables), which means you can
+write more than one `[[bin]]` section to make several executables in your crate.
+
+The example below uses `[lib]`, but it also applies to all other sections
+as well. All values listed are the defaults for that option unless otherwise
+specified.
+
+```toml
+[package]
+# ...
+
+[lib]
+# The name of a target is the name of the library that will be generated. This
+# is defaulted to the name of the package, with any dashes replaced
+# with underscores. (Rust `extern crate` declarations reference this name;
+# therefore the value must be a valid Rust identifier to be usable.)
+name = "foo"
+
+# This field points at where the crate is located, relative to the `Cargo.toml`.
+path = "src/lib.rs"
+
+# A flag for enabling unit tests for this target. This is used by `cargo test`.
+test = true
+
+# A flag for enabling documentation tests for this target. This is only relevant
+# for libraries, it has no effect on other sections. This is used by
+# `cargo test`.
+doctest = true
+
+# A flag for enabling benchmarks for this target. This is used by `cargo bench`.
+bench = true
+
+# A flag for enabling documentation of this target. This is used by `cargo doc`.
+doc = true
+
+# If the target is meant to be a compiler plugin, this field must be set to true
+# for Cargo to correctly compile it and make it available for all dependencies.
+plugin = false
+
+# If the target is meant to be a "macros 1.1" procedural macro, this field must
+# be set to true.
+proc-macro = false
+
+# If set to false, `cargo test` will omit the `--test` flag to rustc, which
+# stops it from generating a test harness. This is useful when the binary being
+# built manages the test runner itself.
+harness = true
+
+# If set then a target can be configured to use a different edition than the
+# `[package]` is configured to use, perhaps only compiling a library with the
+# 2018 edition or only compiling one unit test with the 2015 edition. By default
+# all targets are compiled with the edition specified in `[package]`.
+edition = '2015'
+```
+
+The `[package]` also includes the optional `autobins`, `autoexamples`,
+`autotests`, and `autobenches` keys to explicitly opt-in or opt-out of
+auto-discovering specific target kinds.
+
+#### The `required-features` field (optional)
+
+The `required-features` field specifies which features the target needs in order
+to be built. If any of the required features are not selected, the target will
+be skipped. This is only relevant for the `[[bin]]`, `[[bench]]`, `[[test]]`,
+and `[[example]]` sections, it has no effect on `[lib]`.
+
+```toml
+[features]
+# ...
+postgres = []
+sqlite = []
+tools = []
+
+[[bin]]
+# ...
+required-features = ["postgres", "tools"]
+```
+
+#### Building dynamic or static libraries
+
+If your package produces a library, you can specify which kind of library to
+build by explicitly listing the library in your `Cargo.toml`:
+
+```toml
+# ...
+
+[lib]
+name = "..."
+crate-type = ["dylib"] # could be `staticlib` as well
+```
+
+The available options are `dylib`, `rlib`, `staticlib`, `cdylib`, and
+`proc-macro`. You should only use this option in a package. Cargo will always
+compile packages (dependencies) based on the requirements of the package that
+includes them.
+
+You can read more about the different crate types in the
+[Rust Reference Manual](https://doc.rust-lang.org/reference/linkage.html)
+
+### The `[patch]` Section
+
+This section of Cargo.toml can be used to [override dependencies][replace] with
+other copies. The syntax is similar to the `[dependencies]` section:
+
+```toml
+[patch.crates-io]
+foo = { git = 'https://github.com/example/foo' }
+bar = { path = 'my/local/bar' }
+
+[dependencies.baz]
+git = 'https://github.com/example/baz'
+
+[patch.'https://github.com/example/baz']
+baz = { git = 'https://github.com/example/patched-baz', branch = 'my-branch' }
+```
+
+The `[patch]` table is made of dependency-like sub-tables. Each key after
+`[patch]` is a URL of the source that's being patched, or `crates-io` if
+you're modifying the https://crates.io registry. In the example above
+`crates-io` could be replaced with a git URL such as
+`https://github.com/rust-lang-nursery/log`; the second `[patch]`
+section in the example uses this to specify a source called `baz`.
+
+Each entry in these tables is a normal dependency specification, the same as
+found in the `[dependencies]` section of the manifest. The dependencies listed
+in the `[patch]` section are resolved and used to patch the source at the
+URL specified. The above manifest snippet patches the `crates-io` source (e.g.
+crates.io itself) with the `foo` crate and `bar` crate. It also
+patches the `https://github.com/example/baz` source with a `my-branch` that
+comes from elsewhere.
+
+Sources can be patched with versions of crates that do not exist, and they can
+also be patched with versions of crates that already exist. If a source is
+patched with a crate version that already exists in the source, then the
+source's original crate is replaced.
+
+More information about overriding dependencies can be found in the [overriding
+dependencies][replace] section of the documentation and [RFC 1969] for the
+technical specification of this feature.
+
+[RFC 1969]: https://github.com/rust-lang/rfcs/pull/1969
+[replace]: reference/specifying-dependencies.html#overriding-dependencies
+
+### The `[replace]` Section
+
+This section of Cargo.toml can be used to [override dependencies][replace] with
+other copies. The syntax is similar to the `[dependencies]` section:
+
+```toml
+[replace]
+"foo:0.1.0" = { git = 'https://github.com/example/foo' }
+"bar:1.0.2" = { path = 'my/local/bar' }
+```
+
+Each key in the `[replace]` table is a [package id
+specification](reference/pkgid-spec.html) which allows arbitrarily choosing a node in the
+dependency graph to override. The value of each key is the same as the
+`[dependencies]` syntax for specifying dependencies, except that you can't
+specify features. Note that when a crate is overridden the copy it's overridden
+with must have both the same name and version, but it can come from a different
+source (e.g. git or a local path).
+
+More information about overriding dependencies can be found in the [overriding
+dependencies][replace] section of the documentation.

+## Package ID Specifications
+
+### Package ID specifications
+
+Subcommands of Cargo frequently need to refer to a particular package within a
+dependency graph for various operations like updating, cleaning, building, etc.
+To solve this problem, Cargo supports Package ID Specifications. A specification
+is a string which is used to uniquely refer to one package within a graph of
+packages.
+
+#### Specification grammar
+
+The formal grammar for a Package Id Specification is:
+
+```notrust
+pkgid := pkgname
+ | [ proto "://" ] hostname-and-path [ "#" ( pkgname | semver ) ]
+pkgname := name [ ":" semver ]
+
+proto := "http" | "git" | ...
+```
+
+Here, brackets indicate that the contents are optional.
+
+#### Example specifications
+
+These could all be references to a package `foo` version `1.2.3` from the
+registry at `crates.io`
+
+| pkgid | name | version | url |
+|:-----------------------------|:-----:|:-------:|:----------------------:|
+| `foo` | `foo` | `*` | `*` |
+| `foo:1.2.3` | `foo` | `1.2.3` | `*` |
+| `crates.io/foo` | `foo` | `*` | `*://crates.io/foo` |
+| `crates.io/foo#1.2.3` | `foo` | `1.2.3` | `*://crates.io/foo` |
+| `crates.io/bar#foo:1.2.3` | `foo` | `1.2.3` | `*://crates.io/bar` |
+| `http://crates.io/foo#1.2.3` | `foo` | `1.2.3` | `http://crates.io/foo` |
+
+#### Brevity of specifications
+
+The goal of this is to enable both succinct and exhaustive syntaxes for
+referring to packages in a dependency graph. Ambiguous references may refer to
+one or more packages. Most commands generate an error if more than one package
+could be referred to with the same specification.
--- /dev/null
+## Publishing on crates.io
+
+Once you've got a library that you'd like to share with the world, it's time to
+publish it on [crates.io]! Publishing a crate is when a specific
+version is uploaded to be hosted on [crates.io].
+
+Take care when publishing a crate, because a publish is **permanent**. The
+version can never be overwritten, and the code cannot be deleted. There is no
+limit to the number of versions which can be published, however.
+
+### Before your first publish
+
+First thing’s first, you’ll need an account on [crates.io] to acquire
+an API token. To do so, [visit the home page][crates.io] and log in via a GitHub
+account (required for now). After this, visit your [Account
+Settings](https://crates.io/me) page and run the `cargo login` command
+specified.
+
+```console
+$ cargo login abcdefghijklmnopqrstuvwxyz012345
+```
+
+This command will inform Cargo of your API token and store it locally in your
+`~/.cargo/credentials` (previously it was `~/.cargo/config`). Note that this
+token is a **secret** and should not be shared with anyone else. If it leaks for
+any reason, you should regenerate it immediately.
+
+### Before publishing a new crate
+
+Keep in mind that crate names on [crates.io] are allocated on a first-come-first-
+serve basis. Once a crate name is taken, it cannot be used for another crate.
+
+#### Packaging a crate
+
+The next step is to package up your crate into a format that can be uploaded to
+[crates.io]. For this we’ll use the `cargo package` subcommand. This will take
+our entire crate and package it all up into a `*.crate` file in the
+`target/package` directory.
+
+```console
+$ cargo package
+```
+
+As an added bonus, the `*.crate` will be verified independently of the current
+source tree. After the `*.crate` is created, it’s unpacked into
+`target/package` and then built from scratch to ensure that all necessary files
+are there for the build to succeed. This behavior can be disabled with the
+`--no-verify` flag.
+
+Now’s a good time to take a look at the `*.crate` file to make sure you didn’t
+accidentally package up that 2GB video asset, or large data files used for code
+generation, integration tests, or benchmarking. There is currently a 10MB
+upload size limit on `*.crate` files. So, if the size of `tests` and `benches`
+directories and their dependencies are up to a couple of MBs, you can keep them
+in your package; otherwise, better to exclude them.
+
+Cargo will automatically ignore files ignored by your version control system
+when packaging, but if you want to specify an extra set of files to ignore you
+can use the `exclude` key in the manifest:
+
+```toml
+[package]
+# ...
+exclude = [
+ "public/assets/*",
+ "videos/*",
+]
+```
+
+The syntax of each element in this array is what
+[rust-lang/glob](https://github.com/rust-lang/glob) accepts. If you’d rather
+roll with a whitelist instead of a blacklist, Cargo also supports an `include`
+key, which if set, overrides the `exclude` key:
+
+```toml
+[package]
+# ...
+include = [
+ "**/*.rs",
+ "Cargo.toml",
+]
+```
+
+### Uploading the crate
+
+Now that we’ve got a `*.crate` file ready to go, it can be uploaded to
+[crates.io] with the `cargo publish` command. And that’s it, you’ve now published
+your first crate!
+
+```console
+$ cargo publish
+```
+
+If you’d like to skip the `cargo package` step, the `cargo publish` subcommand
+will automatically package up the local crate if a copy isn’t found already.
+
+Be sure to check out the [metadata you can
+specify](reference/manifest.html#package-metadata) to ensure your crate can be
+discovered more easily!
+
+### Publishing a new version of an existing crate
+
+In order to release a new version, change the `version` value specified in your
+`Cargo.toml` manifest. Keep in mind [the semver
+rules](reference/manifest.html#the-version-field). Then optionally run `cargo package` if
+you want to inspect the `*.crate` file for the new version before publishing,
+and run `cargo publish` to upload the new version.
+
+### Managing a crates.io-based crate
+
+Management of crates is primarily done through the command line `cargo` tool
+rather than the [crates.io] web interface. For this, there are a few subcommands
+to manage a crate.
+
+#### `cargo yank`
+
+Occasions may arise where you publish a version of a crate that actually ends up
+being broken for one reason or another (syntax error, forgot to include a file,
+etc.). For situations such as this, Cargo supports a “yank” of a version of a
+crate.
+
+```console
+$ cargo yank --vers 1.0.1
+$ cargo yank --vers 1.0.1 --undo
+```
+
+A yank **does not** delete any code. This feature is not intended for deleting
+accidentally uploaded secrets, for example. If that happens, you must reset
+those secrets immediately.
+
+The semantics of a yanked version are that no new dependencies can be created
+against that version, but all existing dependencies continue to work. One of the
+major goals of [crates.io] is to act as a permanent archive of crates that does
+not change over time, and allowing deletion of a version would go against this
+goal. Essentially a yank means that all packages with a `Cargo.lock` will not
+break, while any future `Cargo.lock` files generated will not list the yanked
+version.
+
+#### `cargo owner`
+
+A crate is often developed by more than one person, or the primary maintainer
+may change over time! The owner of a crate is the only person allowed to publish
+new versions of the crate, but an owner may designate additional owners.
+
+```console
+$ cargo owner --add my-buddy
+$ cargo owner --remove my-buddy
+$ cargo owner --add github:rust-lang:owners
+$ cargo owner --remove github:rust-lang:owners
+```
+
+The owner IDs given to these commands must be GitHub user names or GitHub teams.
+
+If a user name is given to `--add`, that user becomes a “named” owner, with
+full rights to the crate. In addition to being able to publish or yank versions
+of the crate, they have the ability to add or remove owners, *including* the
+owner that made *them* an owner. Needless to say, you shouldn’t make people you
+don’t fully trust into a named owner. In order to become a named owner, a user
+must have logged into [crates.io] previously.
+
+If a team name is given to `--add`, that team becomes a “team” owner, with
+restricted right to the crate. While they have permission to publish or yank
+versions of the crate, they *do not* have the ability to add or remove owners.
+In addition to being more convenient for managing groups of owners, teams are
+just a bit more secure against owners becoming malicious.
+
+The syntax for teams is currently `github:org:team` (see examples above).
+In order to add a team as an owner one must be a member of that team. No
+such restriction applies to removing a team as an owner.
+
+### GitHub permissions
+
+Team membership is not something GitHub provides simple public access to, and it
+is likely for you to encounter the following message when working with them:
+
+> It looks like you don’t have permission to query a necessary property from
+GitHub to complete this request. You may need to re-authenticate on [crates.io]
+to grant permission to read GitHub org memberships. Just go to
+https://crates.io/login
+
+This is basically a catch-all for “you tried to query a team, and one of the
+five levels of membership access control denied this”. That is not an
+exaggeration. GitHub’s support for team access control is Enterprise Grade.
+
+The most likely cause of this is simply that you last logged in before this
+feature was added. We originally requested *no* permissions from GitHub when
+authenticating users, because we didn’t actually ever use the user’s token for
+anything other than logging them in. However to query team membership on your
+behalf, we now require [the `read:org` scope][oauth-scopes].
+
+You are free to deny us this scope, and everything that worked before teams
+were introduced will keep working. However you will never be able to add a team
+as an owner, or publish a crate as a team owner. If you ever attempt to do this,
+you will get the error above. You may also see this error if you ever try to
+publish a crate that you don’t own at all, but otherwise happens to have a team.
+
+If you ever change your mind, or just aren’t sure if [crates.io] has sufficient
+permission, you can always go to https://crates.io/login, which will prompt you
+for permission if [crates.io] doesn’t have all the scopes it would like to.
+
+An additional barrier to querying GitHub is that the organization may be
+actively denying third party access. To check this, you can go to:
+
+ https://github.com/organizations/:org/settings/oauth_application_policy
+
+where `:org` is the name of the organization (e.g. rust-lang). You may see
+something like:
+
+
+
+Where you may choose to explicitly remove [crates.io] from your organization’s
+blacklist, or simply press the “Remove Restrictions” button to allow all third
+party applications to access this data.
+
+Alternatively, when [crates.io] requested the `read:org` scope, you could have
+explicitly whitelisted [crates.io] querying the org in question by pressing
+the “Grant Access” button next to its name:
+
+
+
+[crates.io]: https://crates.io/
+[oauth-scopes]: https://developer.github.com/apps/building-oauth-apps/understanding-scopes-for-oauth-apps/

+## Source Replacement
+
+This document is about replacing the crate index. You can read about overriding
+dependencies in the [overriding dependencies][overriding] section of this
+documentation.
+
+Cargo supports the ability to **replace one source with another** to express
+strategies along the lines of mirrors or vendoring dependencies. Configuration
+is currently done through the [`.cargo/config` configuration][config] mechanism,
+like so:
+
+[config]: reference/config.html
+
+```toml
+# The `source` table is where all keys related to source-replacement
+# are stored.
+[source]
+
+# Under the `source` table are a number of other tables whose keys are a
+# name for the relevant source. For example this section defines a new
+# source, called `my-awesome-source`, which comes from a directory
+# located at `vendor` relative to the directory containing this `.cargo/config`
+# file
+[source.my-awesome-source]
+directory = "vendor"
+
+# Git sources can optionally specify a branch/tag/rev as well
+git = "https://example.com/path/to/repo"
+# branch = "master"
+# tag = "v1.0.1"
+# rev = "313f44e8"
+
+# The crates.io default source for crates is available under the name
+# "crates-io", and here we use the `replace-with` key to indicate that it's
+# replaced with our source above.
+[source.crates-io]
+replace-with = "my-awesome-source"
+```
+
+With this configuration Cargo attempts to look up all crates in the directory
+"vendor" rather than querying the online registry at crates.io. Using source
+replacement Cargo can express:
+
+* Vendoring - custom sources can be defined which represent crates on the local
+ filesystem. These sources are subsets of the source that they're replacing and
+ can be checked into packages if necessary.
+
+* Mirroring - sources can be replaced with an equivalent version which acts as a
+ cache for crates.io itself.
+
+Cargo has a core assumption about source replacement that the source code is
+exactly the same from both sources. In our above example Cargo assumes that all
+of the crates coming from `my-awesome-source` are the exact same as the copies
+from `crates-io`. Note that this also means that `my-awesome-source` is not
+allowed to have crates which are not present in the `crates-io` source.
+
+As a consequence, source replacement is not appropriate for situations such as
+patching a dependency or a private registry. Cargo supports patching
+dependencies through the usage of [the `[replace]` key][replace-section], and
+private registry support is planned for a future version of Cargo.
+
+[replace-section]: reference/manifest.html#the-replace-section
+[overriding]: reference/specifying-dependencies.html#overriding-dependencies
+
+### Configuration
+
+Configuration of replacement sources is done through [`.cargo/config`][config]
+and the full set of available keys are:
+
+```toml
+# Each source has its own table where the key is the name of the source
+[source.the-source-name]
+
+# Indicate that `the-source-name` will be replaced with `another-source`,
+# defined elsewhere
+replace-with = "another-source"
+
+# Available kinds of sources that can be specified (described below)
+registry = "https://example.com/path/to/index"
+local-registry = "path/to/registry"
+directory = "path/to/vendor"
+```
+
+The `crates-io` represents the crates.io online registry (default source of
+crates) and can be replaced with:
+
+```toml
+[source.crates-io]
+replace-with = 'another-source'
+```
+
+### Registry Sources
+
+A "registry source" is one that is the same as crates.io itself. That is, it has
+an index served in a git repository which matches the format of the
+[crates.io index](https://github.com/rust-lang/crates.io-index). That repository
+then has configuration indicating where to download crates from.
+
+Currently there is not an already-available project for setting up a mirror of
+crates.io. Stay tuned though!
+
+### Local Registry Sources
+
+A "local registry source" is intended to be a subset of another registry
+source, but available on the local filesystem (aka vendoring). Local registries
+are downloaded ahead of time, typically sync'd with a `Cargo.lock`, and are
+made up of a set of `*.crate` files and an index like the normal registry is.
+
+The primary way to manage and create local registry sources is through the
+[`cargo-local-registry`][cargo-local-registry] subcommand, available on
+crates.io and can be installed with `cargo install cargo-local-registry`.
+
+[cargo-local-registry]: https://crates.io/crates/cargo-local-registry
+
+Local registries are contained within one directory and contain a number of
+`*.crate` files downloaded from crates.io as well as an `index` directory with
+the same format as the crates.io-index project (populated with just entries for
+the crates that are present).
+
+### Directory Sources
+
+A "directory source" is similar to a local registry source where it contains a
+number of crates available on the local filesystem, suitable for vendoring
+dependencies. Also like local registries, directory sources can primarily be
+managed by an external subcommand, [`cargo-vendor`][cargo-vendor], which can be
+installed with `cargo install cargo-vendor`.
+
+[cargo-vendor]: https://crates.io/crates/cargo-vendor
+
+Directory sources are distinct from local registries though in that they contain
+the unpacked version of `*.crate` files, making it more suitable in some
+situations to check everything into source control. A directory source is just a
+directory containing a number of other directories which contain the source code
+for crates (the unpacked version of `*.crate` files). Currently no restriction
+is placed on the name of each directory.
+
+Each crate in a directory source also has an associated metadata file indicating
+the checksum of each file in the crate to protect against accidental
+modifications.
--- /dev/null
+## Specifying Dependencies
+
+Your crates can depend on other libraries from [crates.io], `git` repositories, or
+subdirectories on your local file system. You can also temporarily override the
+location of a dependency— for example, to be able to test out a bug fix in the
+dependency that you are working on locally. You can have different
+dependencies for different platforms, and dependencies that are only used during
+development. Let's take a look at how to do each of these.
+
+### Specifying dependencies from crates.io
+
+Cargo is configured to look for dependencies on [crates.io] by default. Only
+the name and a version string are required in this case. In [the cargo
+guide](guide/index.html), we specified a dependency on the `time` crate:
+
+```toml
+[dependencies]
+time = "0.1.12"
+```
+
+The string `"0.1.12"` is a [semver] version requirement. Since this
+string does not have any operators in it, it is interpreted the same way as
+if we had specified `"^0.1.12"`, which is called a caret requirement.
+
+[semver]: https://github.com/steveklabnik/semver#requirements
+
+### Caret requirements
+
+**Caret requirements** allow SemVer compatible updates to a specified version.
+An update is allowed if the new version number does not modify the left-most
+non-zero digit in the major, minor, patch grouping. In this case, if we ran
+`cargo update -p time`, cargo should update us to version `0.1.13` if it is the
+latest `0.1.z` release, but would not update us to `0.2.0`. If instead we had
+specified the version string as `^1.0`, cargo should update to `1.1` if it is
+the latest `1.y` release, but not `2.0`. The version `0.0.x` is not considered
+compatible with any other version.
+
+Here are some more examples of caret requirements and the versions that would
+be allowed with them:
+
+```notrust
+^1.2.3 := >=1.2.3 <2.0.0
+^1.2 := >=1.2.0 <2.0.0
+^1 := >=1.0.0 <2.0.0
+^0.2.3 := >=0.2.3 <0.3.0
+^0.2 := >= 0.2.0 < 0.3.0
+^0.0.3 := >=0.0.3 <0.0.4
+^0.0 := >=0.0.0 <0.1.0
+^0 := >=0.0.0 <1.0.0
+```
+
+This compatibility convention is different from SemVer in the way it treats
+versions before 1.0.0. While SemVer says there is no compatibility before
+1.0.0, Cargo considers `0.x.y` to be compatible with `0.x.z`, where `y ≥ z`
+and `x > 0`.
+
+### Tilde requirements
+
+**Tilde requirements** specify a minimal version with some ability to update.
+If you specify a major, minor, and patch version or only a major and minor
+version, only patch-level changes are allowed. If you only specify a major
+version, then minor- and patch-level changes are allowed.
+
+`~1.2.3` is an example of a tilde requirement.
+
+```notrust
+~1.2.3 := >=1.2.3 <1.3.0
+~1.2 := >=1.2.0 <1.3.0
+~1 := >=1.0.0 <2.0.0
+```
+
+### Wildcard requirements
+
+**Wildcard requirements** allow for any version where the wildcard is
+positioned.
+
+`*`, `1.*` and `1.2.*` are examples of wildcard requirements.
+
+```notrust
+* := >=0.0.0
+1.* := >=1.0.0 <2.0.0
+1.2.* := >=1.2.0 <1.3.0
+```
+
+### Inequality requirements
+
+**Inequality requirements** allow manually specifying a version range or an
+exact version to depend on.
+
+Here are some examples of inequality requirements:
+
+```notrust
+>= 1.2.0
+> 1
+< 2
+= 1.2.3
+```
+
+### Multiple requirements
+
+Multiple version requirements can also be separated with a comma, e.g. `>= 1.2,
+< 1.5`.
+
+### Specifying dependencies from `git` repositories
+
+To depend on a library located in a `git` repository, the minimum information
+you need to specify is the location of the repository with the `git` key:
+
+```toml
+[dependencies]
+rand = { git = "https://github.com/rust-lang-nursery/rand" }
+```
+
+Cargo will fetch the `git` repository at this location then look for a
+`Cargo.toml` for the requested crate anywhere inside the `git` repository
+(not necessarily at the root).
+
+Since we haven’t specified any other information, Cargo assumes that
+we intend to use the latest commit on the `master` branch to build our package.
+You can combine the `git` key with the `rev`, `tag`, or `branch` keys to
+specify something else. Here's an example of specifying that you want to use
+the latest commit on a branch named `next`:
+
+```toml
+[dependencies]
+rand = { git = "https://github.com/rust-lang-nursery/rand", branch = "next" }
+```
+
+### Specifying path dependencies
+
+Over time, our `hello_world` package from [the guide](guide/index.html) has
+grown significantly in size! It’s gotten to the point that we probably want to
+split out a separate crate for others to use. To do this Cargo supports **path
+dependencies** which are typically sub-crates that live within one repository.
+Let’s start off by making a new crate inside of our `hello_world` package:
+
+```console
+# inside of hello_world/
+$ cargo new hello_utils
+```
+
+This will create a new folder `hello_utils` inside of which a `Cargo.toml` and
+`src` folder are ready to be configured. In order to tell Cargo about this, open
+up `hello_world/Cargo.toml` and add `hello_utils` to your dependencies:
+
+```toml
+[dependencies]
+hello_utils = { path = "hello_utils" }
+```
+
+This tells Cargo that we depend on a crate called `hello_utils` which is found
+in the `hello_utils` folder (relative to the `Cargo.toml` it’s written in).
+
+And that’s it! The next `cargo build` will automatically build `hello_utils` and
+all of its own dependencies, and others can also start using the crate as well.
+However, crates that use dependencies specified with only a path are not
+permitted on [crates.io]. If we wanted to publish our `hello_world` crate, we
+would need to publish a version of `hello_utils` to [crates.io](https://crates.io)
+and specify its version in the dependencies line as well:
+
+```toml
+[dependencies]
+hello_utils = { path = "hello_utils", version = "0.1.0" }
+```
+
+### Overriding dependencies
+
+There are a number of methods in Cargo to support overriding dependencies and
+otherwise controlling the dependency graph. These options are typically, though,
+only available at the workspace level and aren't propagated through
+dependencies. In other words, "applications" have the ability to override
+dependencies but "libraries" do not.
+
+The desire to override a dependency or otherwise alter some dependencies can
+arise through a number of scenarios. Most of them, however, boil down to the
+ability to work with a crate before it's been published to crates.io. For
+example:
+
+* A crate you're working on is also used in a much larger application you're
+ working on, and you'd like to test a bug fix to the library inside of the
+ larger application.
+* An upstream crate you don't work on has a new feature or a bug fix on the
+ master branch of its git repository which you'd like to test out.
+* You're about to publish a new major version of your crate, but you'd like to
+ do integration testing across an entire package to ensure the new major
+ version works.
+* You've submitted a fix to an upstream crate for a bug you found, but you'd
+ like to immediately have your application start depending on the fixed version
+ of the crate to avoid blocking on the bug fix getting merged.
+
+These scenarios are currently all solved with the [`[patch]` manifest
+section][patch-section]. Historically some of these scenarios have been solved
+with [the `[replace]` section][replace-section], but we'll document the `[patch]`
+section here.
+
+[patch-section]: reference/manifest.html#the-patch-section
+[replace-section]: reference/manifest.html#the-replace-section
+
+### Testing a bugfix
+
+Let's say you're working with the [`uuid` crate] but while you're working on it
+you discover a bug. You are, however, quite enterprising so you decide to also
+try out to fix the bug! Originally your manifest will look like:
+
+[`uuid` crate]: https://crates.io/crates/uuid
+
+```toml
+[package]
+name = "my-library"
+version = "0.1.0"
+authors = ["..."]
+
+[dependencies]
+uuid = "1.0"
+```
+
+First thing we'll do is to clone the [`uuid` repository][uuid-repository]
+locally via:
+
+```console
+$ git clone https://github.com/rust-lang-nursery/uuid
+```
+
+Next we'll edit the manifest of `my-library` to contain:
+
+```toml
+[patch.crates-io]
+uuid = { path = "../path/to/uuid" }
+```
+
+Here we declare that we're *patching* the source `crates-io` with a new
+dependency. This will effectively add the local checked out version of `uuid` to
+the crates.io registry for our local package.
+
+Next up we need to ensure that our lock file is updated to use this new version
+of `uuid` so our package uses the locally checked out copy instead of one from
+crates.io. The way `[patch]` works is that it'll load the dependency at
+`../path/to/uuid` and then whenever crates.io is queried for versions of `uuid`
+it'll *also* return the local version.
+
+This means that the version number of the local checkout is significant and will
+affect whether the patch is used. Our manifest declared `uuid = "1.0"` which
+means we'll only resolve to `>= 1.0.0, < 2.0.0`, and Cargo's greedy resolution
+algorithm also means that we'll resolve to the maximum version within that
+range. Typically this doesn't matter as the version of the git repository will
+already be greater or match the maximum version published on crates.io, but it's
+important to keep this in mind!
+
+In any case, typically all you need to do now is:
+
+```console
+$ cargo build
+ Compiling uuid v1.0.0 (.../uuid)
+ Compiling my-library v0.1.0 (.../my-library)
+ Finished dev [unoptimized + debuginfo] target(s) in 0.32 secs
+```
+
+And that's it! You're now building with the local version of `uuid` (note the
+path in parentheses in the build output). If you don't see the local path version getting
+built then you may need to run `cargo update -p uuid --precise $version` where
+`$version` is the version of the locally checked out copy of `uuid`.
+
+Once you've fixed the bug you originally found the next thing you'll want to do
+is to likely submit that as a pull request to the `uuid` crate itself. Once
+you've done this then you can also update the `[patch]` section. The listing
+inside of `[patch]` is just like the `[dependencies]` section, so once your pull
+request is merged you could change your `path` dependency to:
+
+```toml
+[patch.crates-io]
+uuid = { git = 'https://github.com/rust-lang-nursery/uuid' }
+```
+
+[uuid-repository]: https://github.com/rust-lang-nursery/uuid
+
+### Working with an unpublished minor version
+
+Let's now shift gears a bit from bug fixes to adding features. While working on
+`my-library` you discover that a whole new feature is needed in the `uuid`
+crate. You've implemented this feature, tested it locally above with `[patch]`,
+and submitted a pull request. Let's go over how you continue to use and test it
+before it's actually published.
+
+Let's also say that the current version of `uuid` on crates.io is `1.0.0`, but
+since then the master branch of the git repository has updated to `1.0.1`. This
+branch includes your new feature you submitted previously. To use this
+repository we'll edit our `Cargo.toml` to look like
+
+```toml
+[package]
+name = "my-library"
+version = "0.1.0"
+authors = ["..."]
+
+[dependencies]
+uuid = "1.0.1"
+
+[patch.crates-io]
+uuid = { git = 'https://github.com/rust-lang-nursery/uuid' }
+```
+
+Note that our local dependency on `uuid` has been updated to `1.0.1` as it's
+what we'll actually require once the crate is published. This version doesn't
+exist on crates.io, though, so we provide it with the `[patch]` section of the
+manifest.
+
+Now when our library is built it'll fetch `uuid` from the git repository and
+resolve to 1.0.1 inside the repository instead of trying to download a version
+from crates.io. Once 1.0.1 is published on crates.io the `[patch]` section can
+be deleted.
+
+It's also worth noting that `[patch]` applies *transitively*. Let's say you use
+`my-library` in a larger package, such as:
+
+```toml
+[package]
+name = "my-binary"
+version = "0.1.0"
+authors = ["..."]
+
+[dependencies]
+my-library = { git = 'https://example.com/git/my-library' }
+uuid = "1.0"
+
+[patch.crates-io]
+uuid = { git = 'https://github.com/rust-lang-nursery/uuid' }
+```
+
+Remember that `[patch]` is applicable *transitively* but can only be defined at
+the *top level* so we consumers of `my-library` have to repeat the `[patch]` section
+if necessary. Here, though, the new `uuid` crate applies to *both* our dependency on
+`uuid` and the `my-library -> uuid` dependency. The `uuid` crate will be resolved to
+one version for this entire crate graph, 1.0.1, and it'll be pulled from the git
+repository.
+
+#### Overriding repository URL
+
+In case the dependency you want to override isn't loaded from `crates.io`, you'll have to change a bit how you use `[patch]`:
+
+```toml
+[patch."https://github.com/your/repository"]
+my-library = { path = "../my-library/path" }
+```
+
+And that's it!
+
+### Prepublishing a breaking change
+
+As a final scenario, let's take a look at working with a new major version of a
+crate, typically accompanied with breaking changes. Sticking with our previous
+crates, this means that we're going to be creating version 2.0.0 of the `uuid`
+crate. After we've submitted all changes upstream we can update our manifest for
+`my-library` to look like:
+
+```toml
+[dependencies]
+uuid = "2.0"
+
+[patch.crates-io]
+uuid = { git = "https://github.com/rust-lang-nursery/uuid", branch = "2.0.0" }
+```
+
+And that's it! Like with the previous example the 2.0.0 version doesn't actually
+exist on crates.io but we can still put it in through a git dependency through
+the usage of the `[patch]` section. As a thought exercise let's take another
+look at the `my-binary` manifest from above again as well:
+
+```toml
+[package]
+name = "my-binary"
+version = "0.1.0"
+authors = ["..."]
+
+[dependencies]
+my-library = { git = 'https://example.com/git/my-library' }
+uuid = "1.0"
+
+[patch.crates-io]
+uuid = { git = 'https://github.com/rust-lang-nursery/uuid', branch = '2.0.0' }
+```
+
+Note that this will actually resolve to two versions of the `uuid` crate. The
+`my-binary` crate will continue to use the 1.x.y series of the `uuid` crate but
+the `my-library` crate will use the 2.0.0 version of `uuid`. This will allow you
+to gradually roll out breaking changes to a crate through a dependency graph
+without being force to update everything all at once.
+
+### Overriding with local dependencies
+
+Sometimes you're only temporarily working on a crate and you don't want to have
+to modify `Cargo.toml` like with the `[patch]` section above. For this use
+case Cargo offers a much more limited version of overrides called **path
+overrides**.
+
+Path overrides are specified through `.cargo/config` instead of `Cargo.toml`,
+and you can find [more documentation about this configuration][config-docs].
+Inside of `.cargo/config` you'll specify a key called `paths`:
+
+[config-docs]: reference/config.html
+
+```toml
+paths = ["/path/to/uuid"]
+```
+
+This array should be filled with directories that contain a `Cargo.toml`. In
+this instance, we’re just adding `uuid`, so it will be the only one that’s
+overridden. This path can be either absolute or relative to the directory that
+contains the `.cargo` folder.
+
+Path overrides are more restricted than the `[patch]` section, however, in
+that they cannot change the structure of the dependency graph. When a
+path replacement is used then the previous set of dependencies
+must all match exactly to the new `Cargo.toml` specification. For example this
+means that path overrides cannot be used to test out adding a dependency to a
+crate, instead `[patch]` must be used in that situation. As a result usage of a
+path override is typically isolated to quick bug fixes rather than larger
+changes.
+
+Note: using a local configuration to override paths will only work for crates
+that have been published to [crates.io]. You cannot use this feature to tell
+Cargo how to find local unpublished crates.
+
+### Platform specific dependencies
+
+
+Platform-specific dependencies take the same format, but are listed under a
+`target` section. Normally Rust-like `#[cfg]` syntax will be used to define
+these sections:
+
+```toml
+[target.'cfg(windows)'.dependencies]
+winhttp = "0.4.0"
+
+[target.'cfg(unix)'.dependencies]
+openssl = "1.0.1"
+
+[target.'cfg(target_arch = "x86")'.dependencies]
+native = { path = "native/i686" }
+
+[target.'cfg(target_arch = "x86_64")'.dependencies]
+native = { path = "native/x86_64" }
+```
+
+Like with Rust, the syntax here supports the `not`, `any`, and `all` operators
+to combine various cfg name/value pairs. Note that the `cfg` syntax has only
+been available since Cargo 0.9.0 (Rust 1.8.0).
+
+In addition to `#[cfg]` syntax, Cargo also supports listing out the full target
+the dependencies would apply to:
+
+```toml
+[target.x86_64-pc-windows-gnu.dependencies]
+winhttp = "0.4.0"
+
+[target.i686-unknown-linux-gnu.dependencies]
+openssl = "1.0.1"
+```
+
+If you’re using a custom target specification, quote the full path and file
+name:
+
+```toml
+[target."x86_64/windows.json".dependencies]
+winhttp = "0.4.0"
+
+[target."i686/linux.json".dependencies]
+openssl = "1.0.1"
+native = { path = "native/i686" }
+
+[target."x86_64/linux.json".dependencies]
+openssl = "1.0.1"
+native = { path = "native/x86_64" }
+```
+
+### Development dependencies
+
+You can add a `[dev-dependencies]` section to your `Cargo.toml` whose format
+is equivalent to `[dependencies]`:
+
+```toml
+[dev-dependencies]
+tempdir = "0.3"
+```
+
+Dev-dependencies are not used when compiling
+a package for building, but are used for compiling tests, examples, and
+benchmarks.
+
+These dependencies are *not* propagated to other packages which depend on this
+package.
+
+You can also have target-specific development dependencies by using
+`dev-dependencies` in the target section header instead of `dependencies`. For
+example:
+
+```toml
+[target.'cfg(unix)'.dev-dependencies]
+mio = "0.0.1"
+```
+
+[crates.io]: https://crates.io/
+
+### Build dependencies
+
+You can depend on other Cargo-based crates for use in your build scripts.
+Dependencies are declared through the `build-dependencies` section of the
+manifest:
+
+```toml
+[build-dependencies]
+cc = "1.0.3"
+```
+
+The build script **does not** have access to the dependencies listed
+in the `dependencies` or `dev-dependencies` section. Build
+dependencies will likewise not be available to the package itself
+unless listed under the `dependencies` section as well. A package
+itself and its build script are built separately, so their
+dependencies need not coincide. Cargo is kept simpler and cleaner by
+using independent dependencies for independent purposes.
+
+### Choosing features
+
+If a package you depend on offers conditional features, you can
+specify which to use:
+
+```toml
+[dependencies.awesome]
+version = "1.3.5"
+default-features = false # do not include the default features, and optionally
+ # cherry-pick individual features
+features = ["secure-password", "civet"]
+```
+
+More information about features can be found in the
+[manifest documentation](reference/manifest.html#the-features-section).
+
+### Renaming dependencies in `Cargo.toml`
+
+When writing a `[dependencies]` section in `Cargo.toml` the key you write for a
+dependency typically matches up to the name of the crate you import from in the
+code. For some projects, though, you may wish to reference the crate with a
+different name in the code regardless of how it's published on crates.io. For
+example you may wish to:
+
+* Avoid the need to `use foo as bar` in Rust source.
+* Depend on multiple versions of a crate.
+* Depend on crates with the same name from different registries.
+
+To support this Cargo supports a `package` key in the `[dependencies]` section
+of which package should be depended on:
+
+```toml
+[package]
+name = "mypackage"
+version = "0.0.1"
+
+[dependencies]
+foo = "0.1"
+bar = { git = "https://github.com/example/project", package = "foo" }
+baz = { version = "0.1", registry = "custom", package = "foo" }
+```
+
+In this example, three crates are now available in your Rust code:
+
+```rust
+extern crate foo; // crates.io
+extern crate bar; // git repository
+extern crate baz; // registry `custom`
+```
+
+All three of these crates have the package name of `foo` in their own
+`Cargo.toml`, so we're explicitly using the `package` key to inform Cargo that
+we want the `foo` package even though we're calling it something else locally.
+The `package` key, if not specified, defaults to the name of the dependency
+being requested.
+
+Note that if you have an optional dependency like:
+
+```toml
+[dependencies]
+foo = { version = "0.1", package = 'bar', optional = true }
+```
+
+you're depending on the crate `bar` from crates.io, but your crate has a `foo`
+feature instead of a `bar` feature. That is, names of features take after the
+name of the dependency, not the package name, when renamed.
+
+Enabling transitive dependencies works similarly, for example we could add the
+following to the above manifest:
+
+```toml
+[features]
+log-debug = ['foo/log-debug'] # using 'bar/log-debug' would be an error!
+```
--- /dev/null
+## Unstable Features
+
+Experimental Cargo features are only available on the nightly channel. You
+typically use one of the `-Z` flags to enable them. Run `cargo -Z help` to
+see a list of flags available.
+
+`-Z unstable-options` is a generic flag for enabling other unstable
+command-line flags. Options requiring this will be called out below.
+
+Some unstable features will require you to specify the `cargo-features` key in
+`Cargo.toml`.
+
+### Alternate Registries
+* RFC: [#2141](https://github.com/rust-lang/rfcs/blob/master/text/2141-alternative-registries.md)
+* Tracking Issue: [rust-lang/rust#44931](https://github.com/rust-lang/rust/issues/44931)
+
+Alternate registries allow you to use registries other than crates.io.
+
+The name of a registry is defined in `.cargo/config` under the `registries`
+table:
+
+```toml
+[registries]
+my-registry = { index = "https://my-intranet:8080/index" }
+```
+
+Authentication information for alternate registries can be added to
+`.cargo/credentials`:
+
+```toml
+[my-registry]
+token = "api-token"
+```
+
+Inside `Cargo.toml` you can specify which registry a dependency comes from
+using the `registry` key. First you need to include the appropriate
+`cargo-features` at the top of the file:
+
+```toml
+cargo-features = ["alternative-registries"]
+
+[package]
+...
+
+[dependencies]
+other-create = { version = "1.0", registry = "my-registry"}
+```
+
+A `--registry` flag has been added to commands that interact with registries
+such as `publish`, `login`, etc. Example:
+
+```
+cargo +nightly publish -Z unstable-options --registry my-registry
+```
+
+The `publish` field in `Cargo.toml` has been extended to accept a list of
+registries that will restrict publishing only to those registries.
+
+```toml
+[package]
+...
+publish = ["my-registry"]
+```
+
+
+### publish-lockfile
+* Original Issue: [#2263](https://github.com/rust-lang/cargo/issues/2263)
+* PR: [#5093](https://github.com/rust-lang/cargo/pull/5093)
+* Tracking Issue: [#5654](https://github.com/rust-lang/cargo/issues/5654)
+
+When creating a `.crate` file for distribution, Cargo has historically
+not included the `Cargo.lock` file. This can cause problems with
+using `cargo install` with a binary. You can specify that your package
+should include the `Cargo.lock` file when using `cargo package` or `cargo publish`
+by specifying the `publish-lockfile` key in `Cargo.toml`. This also requires the
+appropriate `cargo-features`:
+
+```toml
+cargo-features = ["publish-lockfile"]
+
+[package]
+...
+publish-lockfile = true
+```
+
+
+### Offline Mode
+* Original Issue: [#4686](https://github.com/rust-lang/cargo/issues/4686)
+* Tracking Issue: [#5655](https://github.com/rust-lang/cargo/issues/5655)
+
+The `-Z offline` flag prevents Cargo from attempting to access the network for
+any reason. Typically Cargo will stop with an error if it wants to access the
+network and it is not available.
+
+Beware that this may result in different dependency resolution than online
+mode. Cargo will restrict itself to crates that are available locally, even
+if there might be a newer version as indicated in the local copy of the index.
+
+### no-index-update
+* Original Issue: [#3479](https://github.com/rust-lang/cargo/issues/3479)
+
+The `-Z no-index-update` flag ensures that Cargo does not attempt to update
+the registry index. This is intended for tools such as Crater that issue many
+Cargo commands, and you want to avoid the network latency for updating the
+index each time.
+
+### avoid-dev-deps
+* Original Issue: [#4988](https://github.com/rust-lang/cargo/issues/4988)
+* Stabilization Issue: [#5133](https://github.com/rust-lang/cargo/issues/5133)
+
+When running commands such as `cargo install` or `cargo build`, Cargo
+currently requires dev-dependencies to be downloaded, even if they are not
+used. The `-Z avoid-dev-deps` flag allows Cargo to avoid downloading
+dev-dependencies if they are not needed. The `Cargo.lock` file will not be
+generated if dev-dependencies are skipped.
+
+### minimal-versions
+* Original Issue: [#4100](https://github.com/rust-lang/cargo/issues/4100)
+* Tracking Issue: [#5657](https://github.com/rust-lang/cargo/issues/5657)
+
+When a `Cargo.lock` file is generated, the `-Z minimal-versions` flag will
+resolve the dependencies to the minimum semver version that will satisfy the
+requirements (instead of the greatest version).
+
+The intended use-case of this flag is to check, during continuous integration,
+that the versions specified in Cargo.toml are a correct reflection of the
+minimum versions that you are actually using. That is, if Cargo.toml says
+`foo = "1.0.0"` that you don't accidentally depend on features added only in
+`foo 1.5.0`.
+
+### out-dir
+* Original Issue: [#4875](https://github.com/rust-lang/cargo/issues/4875)
+
+This feature allows you to specify the directory where artifacts will be
+copied to after they are built. Typically artifacts are only written to the
+`target/release` or `target/debug` directories. However, determining the
+exact filename can be tricky since you need to parse JSON output. The
+`--out-dir` flag makes it easier to predictably access the artifacts. Note
+that the artifacts are copied, so the originals are still in the `target`
+directory. Example:
+
+```
+cargo +nightly build --out-dir=out -Z unstable-options
+```
+
+
+### Profile Overrides
+* Tracking Issue: [rust-lang/rust#48683](https://github.com/rust-lang/rust/issues/48683)
+* RFC: [#2282](https://github.com/rust-lang/rfcs/blob/master/text/2282-profile-dependencies.md)
+
+Profiles can be overridden for specific packages and custom build scripts.
+The general format looks like this:
+
+```toml
+cargo-features = ["profile-overrides"]
+
+[package]
+...
+
+[profile.dev]
+opt-level = 0
+debug = true
+
+# the `image` crate will be compiled with -Copt-level=3
+[profile.dev.overrides.image]
+opt-level = 3
+
+# All dependencies (but not this crate itself or any workspace member)
+# will be compiled with -Copt-level=2 . This includes build dependencies.
+[profile.dev.overrides."*"]
+opt-level = 2
+
+# Build scripts and their dependencies will be compiled with -Copt-level=3
+# By default, build scripts use the same rules as the rest of the profile
+[profile.dev.build-override]
+opt-level = 3
+```
+
+Overrides can only be specified for dev and release profiles.
+
+
+### Config Profiles
+* Tracking Issue: [rust-lang/rust#48683](https://github.com/rust-lang/rust/issues/48683)
+* RFC: [#2282](https://github.com/rust-lang/rfcs/blob/master/text/2282-profile-dependencies.md)
+
+Profiles can be specified in `.cargo/config` files. The `-Z config-profile`
+command-line flag is required to use this feature. The format is the same as
+in a `Cargo.toml` manifest. If found in multiple config files, settings will
+be merged using the regular [config hierarchy](reference/config.html#hierarchical-structure).
+Config settings take precedence over manifest settings.
+
+```toml
+[profile.dev]
+opt-level = 3
+```
+
+```
+cargo +nightly build -Z config-profile
+```
+
+
+### Namespaced features
+* Original issue: [#1286](https://github.com/rust-lang/cargo/issues/1286)
+* Tracking Issue: [rust-lang/cargo#5565](https://github.com/rust-lang/cargo/issues/5565)
+
+Currently, it is not possible to have a feature and a dependency with the same
+name in the manifest. If you set `namespaced-features` to `true`, the namespaces
+for features and dependencies are separated. The effect of this is that, in the
+feature requirements, dependencies have to be prefixed with `crate:`. Like this:
+
+```toml
+[package]
+namespaced-features = true
+
+[features]
+bar = ["crate:baz", "foo"]
+foo = []
+
+[dependencies]
+baz = { version = "0.1", optional = true }
+```
+
+To prevent unnecessary boilerplate from having to explicitly declare features
+for each optional dependency, implicit features get created for any optional
+dependencies where a feature of the same name is not defined. However, if
+a feature of the same name as a dependency is defined, that feature must
+include the dependency as a requirement, as `foo = ["crate:foo"]`.
+
+
+### Build-plan
+* Tracking Issue: [rust-lang/cargo#5579](https://github.com/rust-lang/cargo/issues/5579)
+
+The `--build-plan` argument for the `build` command will output JSON with
+information about which commands would be run without actually executing
+anything. This can be useful when integrating with another build tool.
+Example:
+
+```
+cargo +nightly build --build-plan -Z unstable-options
+```
+
+### default-run
+* Original issue: [#2200](https://github.com/rust-lang/cargo/issues/2200)
+
+The `default-run` option in the `[package]` section of the manifest can be used
+to specify a default binary picked by `cargo run`. For example, when there is
+both `src/bin/a.rs` and `src/bin/b.rs`:
+
+```toml
+[package]
+default-run = "a"
+```
+
+### Metabuild
+* Tracking Issue: [rust-lang/rust#49803](https://github.com/rust-lang/rust/issues/49803)
+* RFC: [#2196](https://github.com/rust-lang/rfcs/blob/master/text/2196-metabuild.md)
+
+Metabuild is a feature to have declarative build scripts. Instead of writing
+a `build.rs` script, you specify a list of build dependencies in the
+`metabuild` key in `Cargo.toml`. A build script is automatically generated
+that runs each build dependency in order. Metabuild packages can then read
+metadata from `Cargo.toml` to specify their behavior.
+
+Include `cargo-features` at the top of `Cargo.toml`, a `metadata` key in the
+`package`, list the dependencies in `build-dependencies`, and add any metadata
+that the metabuild packages require. Example:
+
+```toml
+cargo-features = ["metabuild"]
+
+[package]
+name = "mypackage"
+version = "0.0.1"
+metabuild = ["foo", "bar"]
+
+[build-dependencies]
+foo = "1.0"
+bar = "1.0"
+
+[package.metadata.foo]
+extra-info = "qwerty"
+```
+
+Metabuild packages should have a public function called `metabuild` that
+performs the same actions as a regular `build.rs` script would perform.

+.SH DESCRIPTION
+.PP
+Execute all benchmarks of a local package.
+.PP
+All of the trailing arguments are passed to the benchmark binaries
+generated for filtering benchmarks and generally providing options
+configuring how they run.
+.PP
+If the \f[B]\-\-package\f[] argument is given, then \f[I]SPEC\f[] is a
+package id specification which indicates which package should be built.
+If it is not given, then the current package is built.
+For more information on \f[I]SPEC\f[] and its format, see the "cargo
+help pkgid" command.
+.PP
+The \f[B]\-\-jobs\f[] argument affects the building of the benchmark
+executable but does not affect how many jobs are used when running the
+benchmarks.

+.SH SYNOPSIS
+.PP
+\f[I]cargo install\f[] [OPTIONS] <CRATE>
+.PP
+\f[I]cargo install\f[] [OPTIONS] \-\-list
+.SH DESCRIPTION
+.PP
+Install a Rust binary
+.PP
+This command manages Cargo\[aq]s local set of install binary crates.
+Only packages which have [[bin]] targets can be installed, and all
+binaries are installed into the installation root\[aq]s \f[I]bin\f[]
+folder.
+The installation root is determined, in order of precedence, by
+\f[B]\-\-root\f[], \f[I]$CARGO_INSTALL_ROOT\f[], the
+\f[I]install.root\f[] configuration key, and finally the home directory
+(which is either \f[I]$CARGO_HOME\f[] if set or \f[I]$HOME/.cargo\f[] by
+default).
+.PP
+There are multiple sources from which a crate can be installed.
+The default location is crates.io but the \f[B]\-\-git\f[] and
+\f[B]\-\-path\f[] flags can change this source.
+If the source contains more than one package (such as \f[I]crates.io\f[]
+or a git repository with multiple crates) the \f[B]\f[] argument is
+required to indicate which crate should be installed.
+.PP
+Crates from crates.io can optionally specify the version they wish to
+install via the \f[B]\-\-vers\f[] flags, and similarly packages from git
+repositories can optionally specify the branch, tag, or revision that
+should be installed.
+If a crate has multiple binaries, the \f[B]\-\-bin\f[] argument can
+selectively install only one of them, and if you\[aq]d rather install
+examples the \f[B]\-\-example\f[] argument can be used as well.
+.PP
+As a special convenience, omitting the <crate> specification entirely
+will install the crate in the current directory.
+That is, \f[I]install\f[] is equivalent to the more explicit "install
+\-\-path .".
+.PP
+If the source is crates.io or \f[B]\-\-git\f[] then by default the crate will be built in a temporary target directory.
+To avoid this, the target directory can be specified by setting the \f[B]CARGO_TARGET_DIR\f[] environment variable to a relative path.
+In particular, this can be useful for caching build artifacts on continuous integration systems.
+.PP
+The \f[B]\-\-list\f[] option will list all installed packages (and their
+versions).

+The specified target for the current package (or package specified by

+.SH DESCRIPTION
+.PP
+Execute all unit and integration tests of a local package.
+.PP
+All of the trailing arguments are passed to the test binaries generated
+for filtering tests and generally providing options configuring how they
+run.
+For example, this will run all tests with the name \[aq]foo\[aq] in
+their name:
+.IP
+.nf
+\f[C]
+cargo\ test\ foo
+\f[]
+.fi
+.PP
+If the \f[B]\-\-package\f[] argument is given, then \[aq]SPEC\[aq] is a
+package id specification which indicates which package should be tested.
+If it is not given, then the current package is tested.
+For more information on \[aq]SPEC\[aq] and its format, see the "cargo
+help pkgid" command.
+.PP
+The \f[B]\-\-jobs\f[] argument affects the building of the test
+executable but does not affect how many jobs are used when running the
+tests.
+.PP
+Compilation can be configured via the \[aq]test\[aq] profile in the
+manifest.
+.PP
+By default the rust test harness hides output from test execution to
+keep results readable.
+Test output can be recovered (e.g.
+for debugging) by passing \f[B]\-\-nocapture\f[] to the test binaries:

+.PP
+If \f[I]SPEC\f[] is given, then a conservative update of the

+.PP
+If \f[I]PRECISE\f[] is specified, then \f[B]\-\-aggressive\f[] must not

+The argument \f[I]PRECISE\f[] is a string representing a precise

+For example, if the package comes from a git repository, then
+\f[I]PRECISE\f[] would be the exact revision that the repository should
+be updated to.

+warning: path override for crate `a` has altered the original list of
+dependencies; the dependency on `bar` was either added or
+modified to not match the previously resolved version
+
+This is currently allowed but is known to produce buggy behavior with spurious
+recompiles and changes to the crate graph. Path overrides unfortunately were
+never intended to support this feature, so for now this message is just a
+warning. In the future, however, this message will become a hard error.
+
+To change the dependency graph via an override it's recommended to use the
+`[replace]` feature of Cargo instead of the path override feature. This is
+documented online at the url below for more information.

+## Creating a git dependency
+`git::new()` is an easy way to create a new git repository containing a
+project that you can then use as a dependency. It will automatically add all
+the files you specify in the project and commit them to the repository.
+Example:
+
+```
+let git_project = git::new("dep1", |project| {
+ project
+ .file("Cargo.toml", &basic_manifest("dep1"))
+ .file("src/lib.rs", r#"pub fn f() { println!("hi!"); } "#)
+}).unwrap();
+
+// Use the `url()` method to get the file url to the new repository.
+let p = project()
+ .file("Cargo.toml", &format!(r#"
+ [package]
+ name = "a"
+ version = "1.0.0"
+
+ [dependencies]
+ dep1 = {{ git = '{}' }}
+ "#, git_project.url()))
+ .file("src/lib.rs", "extern crate dep1;")
+ .build();
+```
+
+## Manually creating repositories
+`git::repo()` can be used to create a `RepoBuilder` which provides a way of
+adding files to a blank repository and committing them.
+
+If you want to then manipulate the repository (such as adding new files or
+tags), you can use `git2::Repository::open()` to open the repository and then
+use some of the helper functions in this file to interact with the repository.

+# Introduction To `support`
+
+Cargo has a wide variety of integration tests that execute the `cargo` binary
+and verify its behavior. The `support` module contains many helpers to make
+this process easy.
+
+The general form of a test involves creating a "project", running cargo, and
+checking the result. Projects are created with the `ProjectBuilder` where you
+specify some files to create. The general form looks like this:
+
+```
+let p = project()
+ .file("src/main.rs", r#"fn main() { println!("hi!"); }"#)
+ .build();
+```
+
+If you do not specify a `Cargo.toml` manifest using `file()`, one is
+automatically created with a project name of `foo` using `basic_manifest()`.
+
+To run cargo, call the `cargo` method and make assertions on the execution:
+
+```
+p.cargo("run --bin foo")
+ .with_stderr(
+ "\
+[COMPILING] foo [..]
+[FINISHED] [..]
+[RUNNING] `target/debug/foo`
+",
+ )
+ .with_stdout("hi!")
+ .run();
+```
+
+The project creates a mini sandbox under the "cargo integration test"
+directory with each test getting a separate directory such as
+`/path/to/cargo/target/cit/t123/`. Each project appears as a separate
+directory. There is also an empty `home` directory created that will be used
+as a home directory instead of your normal home directory.
+
+See `support::lines_match` for an explanation of the string pattern matching.
+
+Browse the `pub` functions in the `support` module for a variety of other
+helpful utilities.
+
+## Testing Nightly Features
+
+If you are testing a Cargo feature that only works on "nightly" cargo, then
+you need to call `masquerade_as_nightly_cargo` on the process builder like
+this:
+
+```
+p.cargo("build").masquerade_as_nightly_cargo()
+```
+
+If you are testing a feature that only works on *nightly rustc* (such as
+benchmarks), then you should exit the test if it is not running with nightly
+rust, like this:
+
+```
+if !is_nightly() {
+ return;
+}
+```
+
+## Platform-specific Notes
+
+When checking output, use `/` for paths even on Windows: the actual output
+of `\` on Windows will be replaced with `/`.
+
+Be careful when executing binaries on Windows. You should not rename, delete,
+or overwrite a binary immediately after running it. Under some conditions
+Windows will fail with errors like "directory not empty" or "failed to remove"
+or "access is denied".
+
+## Specifying Dependencies
+
+You should not write any tests that use the network such as contacting
+crates.io. Typically, simple path dependencies are the easiest way to add a
+dependency. Example:
+
+```
+let p = project()
+ .file("Cargo.toml", r#"
+ [package]
+ name = "foo"
+ version = "1.0.0"
+
+ [dependencies]
+ bar = {path = "bar"}
+ "#)
+ .file("src/lib.rs", "extern crate bar;")
+ .file("bar/Cargo.toml", &basic_manifest("bar", "1.0.0"))
+ .file("bar/src/lib.rs", "")
+ .build();
+```
+
+If you need to test with registry dependencies, see
+`support::registry::Package` for creating packages you can depend on.
+
+If you need to test git dependencies, see `support::git` to create a git
+dependency.

+/// A builder for creating a new package in a registry.
+///
+/// This uses "source replacement" using an automatically generated
+/// `.cargo/config` file to ensure that dependencies will use these packages
+/// instead of contacting crates.io. See `source-replacement.md` for more
+/// details on how source replacement works.
+///
+/// Call `publish` to finalize and create the package.
+///
+/// If no files are specified, an empty `lib.rs` file is automatically created.
+///
+/// The `Cargo.toml` file is automatically generated based on the methods
+/// called on `Package` (for example, calling `dep()` will add to the
+/// `[dependencies]` automatically). You may also specify a `Cargo.toml` file
+/// to override the generated one.
+///
+/// This supports different registry types:
+/// - Regular source replacement that replaces `crates.io` (the default).
+/// - A "local registry" which is a subset for vendoring (see
+/// `Package::local`).
+/// - An "alternative registry" which requires specifying the registry name
+/// (see `Package::alternative`).
+///
+/// This does not support "directory sources". See `directory.rs` for
+/// `VendorPackage` which implements directory sources.
+///
+/// # Example
+/// ```
+/// // Publish package "a" depending on "b".
+/// Package::new("a", "1.0.0")
+/// .dep("b", "1.0.0")
+/// .file("src/lib.rs", r#"
+/// extern crate b;
+/// pub fn f() -> i32 { b::f() * 2 }
+/// "#)
+/// .publish();
+///
+/// // Publish package "b".
+/// Package::new("b", "1.0.0")
+/// .file("src/lib.rs", r#"
+/// pub fn f() -> i32 { 12 }
+/// "#)
+/// .publish();
+///
+/// // Create a project that uses package "a".
+/// let p = project()
+/// .file("Cargo.toml", r#"
+/// [package]
+/// name = "foo"
+/// version = "0.0.1"
+///
+/// [dependencies]
+/// a = "1.0"
+/// "#)
+/// .file("src/main.rs", r#"
