+has no artificial limits like the 1024 character limit for implicit keys.
+
+libfyaml is using https://github.com/yaml/yaml-test-suite as a core part
+of it's testsuite.
+
+## Features
+* Fully supports YAML version 1.2.
+* Attempts to adhere to features coming with YAML version 1.3 so that it
+ will be ready.
+* Zero content copy operation, which means that content is never copied to
+ internal structures. On input types that support it (mmap files and
+ constant strings) that means that memory usage is kept low, and arbitrary
+ large content can be manipulated without problem.
+* Parser may be used in event mode (like libyaml) or in document generating mode.
+* Extensive programmable API capable of manipulating parsed YAML documents or
+ creating them from scratch.
+* YAML emitter with programmable options, supporting colored output.
+* Extensive testsuite for the API, the full YAML test-suite and correct
+ emitter operation.
+* Easy printf/scanf based YAML creation and data extraction API.
+* Accurate and descriptive error messages, in standard compiler format that
+ can be parsed by editors and developer GUIs.
+* Testsuite supports running under valgrind and checking for memory leaks. No
+ leaks should be possible under normal operation, so it is usable for long-
+ running applications.

+
+## Prerequisites
+
+libfyaml is primarily developed on Linux based debian distros but Apple MacOS X builds
+(using homebrew) are supported as well.
+
+On a based debian distro (i.e. ubuntu 19.04 disco) you should install the following
+dependencies:
+
+* `sudo apt-get install gcc autoconf automake libtool git make libltdl-dev pkg-config`
+
+To enable the libyaml comparison checker:
+
+* `sudo apt-get install libyaml-dev`
+
+For the API testsuite libcheck is required:
+
+* `sudo apt-get install check`
+
+And finally in order to build the sphinx based documentation:
+
+* `sudo apt-get install python3 python3-pip python3-setuptools`
+* `pip3 install wheel sphinx git+http://github.com/return42/linuxdoc.git sphinx\_rtd\_theme sphinx-markdown-builder`
+
+Note that some older distros (like xenial) do not have a sufficiently recent
+sphinx in their repos. In that case you can create a virtual environment
+using scripts/create-virtual-env
+
+## Building
+
+``libfyaml`` uses a standard autotools based build scheme so:
+
+* `./bootstrap.sh`
+* `./configure`
+* `make`
+
+Will build the library and `fy-tool`.
+
+* `make check`
+
+Will run the test-suite.
+
+Binaries, libraries, header files and pkgconfig files maybe installed with
+
+* `make install`
+
+By default, the installation prefix will be `/usr/local`, which you can change
+with the `--prefix <dir>` option during configure.
+
+To build the documentation API in HTML format use:
+
+* `make doc-html`
+
+The documentation for the public API will be found in doc/\_build/html
+
+* `make doc-latexpdf`
+
+Will generate a single pdf containing everything.
+
+## Usage and examples
+
+Usage of libfyaml is somewhat similar to libyaml, but with a few notable differences.
+
+1. The objects of the library are opaque, they are pointers that may be used but
+ may not be derefenced via library users. This makes the public API not be dependent of
+ internal changes in the library structures.
+
+2. The object pointers used are guaranteed to not 'move' like libyaml object pointers
+ so you may embed them freely in your own structures.
+
+3. The convenience methods of libyaml allow you to avoid tedious iteration and code
+ duplication. While fully manual YAML document tree manipulation is available, if your
+ application is not performance sensitive when manipulating YAML, you are advised to
+ use the helpers.
+
+### Using libfyaml in your projects
+
+Typically you only have to include the single header file `libfyaml.h` and
+link against the correct fyaml-\<major\>-\<minor\> library.
+
+It is recommended to use pkg-config, i.e.
+
+```make
+CFLAGS+= `pkg-config --cflags libfyaml`
+LDFLAGS+= `pkg-config --libs libfyaml`
+```
+
+For use in an automake based project you may use the following fragment
+```bash
+PKG_CHECK_MODULES(LIBFYAML, [ libfyaml ], HAVE_LIBFYAML=1, HAVE_LIBFYAML=0)
+
+if test "x$HAVE_LIBFYAML" != "x1" ; then
+ AC_MSG_ERROR([failed to find libfyaml])
+fi
+
+AC_SUBST(HAVE_LIBFYAML)
+AC_SUBST(LIBFYAML_CFLAGS)
+AC_SUBST(LIBFYAML_LIBS)
+AC_DEFINE_UNQUOTED([HAVE_LIBFYAML], [$HAVE_LIBFYAML], [Define to 1 if you have libfyaml available])
+AM_CONDITIONAL([HAVE_LIBFYAML], [ test x$HAVE_LIBFYAML = x1 ])
+```
+
+The examples that follow will make things clear.
+
+### Display libfyaml version example

+This is the minimal example that checks that you've compiled against the correct libfyaml.

+
+Parsing and creating a YAML document from either the built-in
+YAML, or an invoice file given on the command line:
+
+```c

+ else
+ fyd = fy_document_build_from_file(NULL, argv[1]);
+ if (!fyd) {
+ fprintf(stderr, "failed to build document");
+ goto fail;
+ }
+```
+
+Get the invoice number and the given name using a single call.
+
+```c
+ /* get the invoice number and the given name */
+ count = fy_document_scanf(fyd,
+ "/invoice %u "
+ "/bill-to/given %256s",
+ &invoice_nr, given);
+ if (count != 2) {

+ goto fail;
+ }
+
+ /* print them as comments in the emitted YAML */
+ printf("# invoice number was %u\n", invoice_nr);
+ printf("# given name is %s\n", given);
+```
+
+In sequence, increase the invoice number, add a spouse and a secondary
+address.
+
+```c
+ rc =
+ /* set increased invoice number (modify existing node) */
+ fy_document_insert_at(fyd, "/invoice",
+ fy_node_buildf(fyd, "%u", invoice_nr + 1)) ||

+ " lines: |\n"
+ " 1226 Windward Ave.\n"));
+ if (rc) {
+ fprintf(stderr, "failed to insert to document\n");
+ goto fail;
+ }
+```
+
+Emit the document to standard output (while sorting the keys)
+

+ if (rc) {

+
+## fy-tool reference
+
+A YAML manipulation tool is included in libfyaml, aptly name `fy-tool`.
+It's a multi tool application, acting differently according to the name it has
+when it's invoked. There are four tool modes, namely:
+
+* fy-testsuite: Used for outputing a test-suite specific event stream which is
+ used for comparison with the expected output of the suite.
+* fy-dump: General purpose YAML parser and dumper, with syntax coloring support,
+ visible whitespace options, and a number of output modes.
+* fy-filter: YAML filtering tool allows to extract information out of a YAML
+ document.
+* fy-join: YAML flexible join tool.
+
+### fy-testsuite usage
+
+A number of options are common in every fy-tool invocation:
+
+```
+Usage : fy-tool [options] [args]
+
+Options:
+
+ --include, -I <path> : Add directory to include path (default path "")
+ --debug-level, -d <lvl> : Set debug level to <lvl>(default level 3)
+ --indent, -i <indent> : Set dump indent to <indent> (default indent 2)
+ --width, -w <width> : Set dump width to <width> (default width 80)
+ --resolve, -r : Perform anchor and merge key resolution (default false)
+ --color, -C <mode> : Color output can be one of on, off, auto (default auto)
+ --visible, -V : Make all whitespace and linebreaks visible (default false)
+ --follow, -l : Follow aliases when using paths (default false)
+ --strip-labels : Strip labels when emitting (default false)
+ --strip-tags : Strip tags when emitting (default false)
+ --strip-doc : Strip document headers and indicators when emitting (default false)
+ --quiet, -q : Quiet operation, do not output messages (default false)
+ --version, -v : Display libfyaml version
+ --help, -h : Display help message
+
+```
+
+```
+Usage: fy-testsuite [options] [args]
+
+ [common options]
+
+ Parse and dump test-suite event format
+ $ fy-testsuite input.yaml
+ ...
+
+ Parse and dump of event example
+ $ echo "foo: bar" | fy-testsuite -
+ +STR
+ +DOC
+ +MAP
+ =VAL :foo
+ =VAL :bar
+ -MAP
+ -DOC
+ -STR
+```
+
+### fy-dump usage
+
+```
+Usage: fy-dump [options] [args]
+
+Options:
+
+ [common options]
+
+ --sort, -s : Perform mapping key sort (valid for dump) (default false)
+ --comment, -c : Output comments (experimental) (default false)
+ --mode, -m <mode> : Output mode can be one of original, block, flow, flow-oneline, json, json-tp, json-oneline (default original)
+ --streaming : Use streaming output mode (default false)
+
+ [common options]
+
+ Parse and dump generated YAML document tree in the original YAML form
+ $ fy-dump input.yaml
+ ...
+
+ Parse and dump generated YAML document tree in block YAML form (and make whitespace visible)
+ $ fy-dump -V -mblock input.yaml
+ ...
+
+ Parse and dump generated YAML document from the input string
+ $ fy-dump -mjson ">foo: bar"
+ {
+ "foo": "bar"
+ }
+
+ Parse and dump generated YAML document from the input string (using streaming mode)
+ $ fy-dump --streaming ">foo: bar"
+ foo: bar
+
+ Note that streaming mode can not perform document validity checks, like duplicate keys nor
+ support the sort keys option.
+```
+
+### fy-filter usage
+
+```
+Usage: fy-filter [options] [args]
+
+Options:
+
+ [common options]
+
+ --sort, -s : Perform mapping key sort (valid for dump) (default false)

+ --file ">foo: bar" is as --file file.yaml with file.yaml "foo: bar"
+
+ Parse and filter YAML document tree starting from the '/foo' path followed by the '/bar' path
+ $ fy-filter --file input.yaml /foo /bar
+ ...
+

+ --mode, -m <mode> : Output mode can be one of original, block, flow, flow-oneline, json, json-tp, json-oneline (default original)
+ --file, -f <file> : Use given file instead of <stdin>
+ Note that using a string with a leading '>' is equivalent to a file with the trailing content
+ --file ">foo: bar" is as --file file.yaml with file.yaml "foo: bar"
+ --to, -T <path> : Join to <path> (default /)

+ ...
+
+ Parse and join two YAML maps
+ $ fy-join ">foo: bar" ">baz: frooz"
+ foo: bar
+ baz: frooz
+```
+
+## Missing features and omissions
+
+1. Windows - libfyaml is not supporting windows yet.
+2. Unicode - libfyaml only supports UTF8 and has no support for wide character input.

+# depending on how configure is run. This is pretty annoying, since

+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,

+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because

+# However there are other variables, like CC, which are often used in

+# This script is derived from GIT-VERSION-GEN from GIT: http://git.or.cz/.
+# It may be run two ways:
+# - from a git repository in which the "git describe" command below
+# produces useful output (thus requiring at least one signed tag)
+# - from a non-git-repo directory containing a .tarball-version file, which
+# presumes this script is invoked like "./git-version-gen .tarball-version".
+
+# In order to use intra-version strings in your project, you will need two
+# separate generated version string files:
+#
+# .tarball-version - present only in a distribution tarball, and not in
+# a checked-out repository. Created with contents that were learned at
+# the last time autoconf was run, and used by git-version-gen. Must not
+# be present in either $(srcdir) or $(builddir) for git-version-gen to
+# give accurate answers during normal development with a checked out tree,
+# but must be present in a tarball when there is no version control system.
+# Therefore, it cannot be used in any dependencies. GNUmakefile has
+# hooks to force a reconfigure at distribution time to get the value
+# correct, without penalizing normal development with extra reconfigures.
+#
+# .version - present in a checked-out repository and in a distribution
+# tarball. Usable in dependencies, particularly for files that don't
+# want to depend on config.h but do want to track version changes.
+# Delete this file prior to any autoconf run where you want to rebuild
+# files to pick up a version string change; and leave it stale to
+# minimize rebuild time after unrelated changes to configure sources.
+#
+# It is probably wise to add these two files to .gitignore, so that you
+# don't accidentally commit either generated file.
+#
+# Use the following line in your configure.ac, so that $(VERSION) will
+# automatically be up-to-date each time configure is run (and note that
+# since configure.ac no longer includes a version string, Makefile rules
+# should not depend on configure.ac for version updates).
+#
+# AC_INIT([GNU project],
+# m4_esyscmd([build-aux/git-version-gen .tarball-version]),
+# [bug-project@example])
+#
+# Then use the following lines in your Makefile.am, so that .version
+# will be present for dependencies, and so that .tarball-version will
+# exist in distribution tarballs.

+## ------ ##
+## Usage. ##
+## ------ ##
+
+# This file is a library for parsing options in your shell scripts along
+# with assorted other useful supporting features that you can make use
+# of too.
+#
+# For the simplest scripts you might need only:
+#
+# #!/bin/sh
+# . relative/path/to/funclib.sh
+# . relative/path/to/options-parser
+# scriptversion=1.0
+# func_options ${1+"$@"}
+# eval set dummy "$func_options_result"; shift
+# ...rest of your script...
+#
+# In order for the '--version' option to work, you will need to have a
+# suitably formatted comment like the one at the top of this file
+# starting with '# Written by ' and ending with '# warranty; '.
+#
+# For '-h' and '--help' to work, you will also need a one line
+# description of your script's purpose in a comment directly above the
+# '# Written by ' line, like the one at the top of this file.
+#
+# The default options also support '--debug', which will turn on shell
+# execution tracing (see the comment above debug_cmd below for another
+# use), and '--verbose' and the func_verbose function to allow your script
+# to display verbose messages only when your user has specified
+# '--verbose'.
+#
+# After sourcing this file, you can plug processing for additional
+# options by amending the variables from the 'Configuration' section
+# below, and following the instructions in the 'Option parsing'
+# section further down.
+
+## -------------- ##
+## Configuration. ##
+## -------------- ##
+
+# You should override these variables in your script after sourcing this
+# file so that they reflect the customisations you have added to the
+# option parser.
+
+# The usage line for option parsing errors and the start of '-h' and
+# '--help' output messages. You can embed shell variables for delayed
+# expansion at the time the message is displayed, but you will need to
+# quote other shell meta-characters carefully to prevent them being
+# expanded when the contents are evaled.
+usage='$progpath [OPTION]...'
+
+# Short help message in response to '-h' and '--help'. Add to this or
+# override it after sourcing this library to reflect the full set of
+# options your script accepts.
+usage_message="\
+ --debug enable verbose shell tracing
+ -W, --warnings=CATEGORY
+ report the warnings falling in CATEGORY [all]
+ -v, --verbose verbosely report processing
+ --version print version information and exit
+ -h, --help print short or long help message and exit
+"
+
+# Additional text appended to 'usage_message' in response to '--help'.
+long_help_message="

+ 'all' show all warnings
+ 'none' turn off all the warnings

+\`configure' configures libfyaml 0.7.3 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+
+Description
+-----------
+
+:program:`fy-tool` is a general YAML/JSON manipulation tool using `libfyaml`.
+Its operation is different depending on how it's called, either via aliases
+named `fy-dump`, `fy-testsuite`, `fy-filter`, `fy-join`, or via the
+`--dump`, `--testsuite`, `--filter`, `--join` options.
+
+* In `dump` mode it will parse YAML/JSON input files and output YAML/JSON
+ according to the output format options.
+
+* In `testsuite` mode it will parse a single YAML input file and output
+ yaml testsuite reference output.
+
+* In `filter` mode it will parse YAML/JSON files and output YAML/JSON
+ output filtered according to the given option.
+
+* In `join` mode it will parse YAML/JSON files and join them into a single
+ YAML/JSON document according to the given command line options.
+
+Options
+-------
+
+.. program:: fy-tool
+
+A number of options are common for all the different modes of operation
+and they are as follows:
+
+.. rubric:: Common options
+
+.. option:: -q, --quiet
+
+ Quiet operation, does not output informational messages at all.
+
+.. option:: -h, --help
+
+ Display usage information.
+
+.. option:: -v, --version
+
+ Display version information.
+
+.. option:: -I DIR, --include=DIR
+
+ Add the `DIR` directory to the search path which will be used to locate a YAML/JSON file.
+ The default path is set to ""
+
+.. option:: -d LEVEL, --debug-level=LEVEL
+
+ Set the minimum numeric debug level value of the library to `LEVEL`.
+ The numeric value must be in the range of 0 to 4 and their meaning is as follows:
+
+ - **0** (`DEBUG`)
+
+ Internal library debugging messages. No output is produced when the
+ library was compiled with `--disable-debug`
+
+ - **1** (`INFO`)
+
+ Informational messages about the internal operation of the library.
+
+ - **2** (`NOTICE`)
+
+ Messsages that could require attention.
+
+ - **3** (`WARNING`)
+
+ A warning message, something is wrong, but operation can continue.
+ This is the default value.
+
+ - **4** (`ERROR`)
+
+ A fatal error occured, it is impossible to continue.
+
+ The default level is 3 (`WARNING`), which means that messages
+ with level 3 and higher will be displayed.
+
+.. rubric:: Parser Options
+
+.. option:: -j JSONOPT, --json=JSONOPT
+
+ Marks the input files as JSON or YAML accordingly to:
+
+ - **no**
+
+ The input files are always in YAML mode.
+
+ - **yes**
+
+ The input files are always set to JSON mode.
+
+ - **auto**
+
+ The input files are set to JSON mode automatically when the
+ file's extension is `.json`. This is the default.
+
+ Note that although libfyaml's YAML 1.2 support is complete, that simply
+ means that a valid JSON file will parse as YAML 1.2. However there
+ are instances where one requires strict JSON spec adherence, and
+ for invalid JSON to be rejected even when it's valid YAML 1.2.
+
+.. option:: --streaming
+
+ Only valid when in **dump** mode, enables streaming mode. This means
+ that no in-memory graph tree is constructed, so indefinite and arbitrary
+ large YAML input streams can be processed.
+
+ Note that in streaming mode:
+
+ - Key duplication checks are disabled.
+ - No reording of key order is possible when emitting (i.e. `--sort` is not available).
+ - Alias resolution is not available (i.e. `--resolve`).
+
+.. rubric:: Resolver Options
+
+.. option:: -r, --resolve
+
+ Perform anchor and merge key resolution. By default this option is disabled.
+
+.. option:: -l, --follow
+
+ Follow aliases when performing path traversal. By default this option is disabled.
+
+.. rubric:: Emitter Options
+
+.. option:: -i INDENT, --indent=INDENT
+
+ Sets the emitter indent (in spaces). Default is **2**.
+
+.. option:: -w WIDTH, --width=WIDTH
+
+ Sets the preferred output width of the emitter. It is generally impossible
+ to strictly adhere to this limit so this is treated as a hint at best.
+ It not valid in any oneline output modes (i.e. `flow-oneline` or `json-oneline`).
+ Default value is 80.
+
+.. option:: -m MODE, --mode=MODE
+
+ Sets the output mode of the YAML emitted. Possible values are:
+
+ - **original**
+
+ The original formatting used in the input. This is default mode.
+
+ - **block**
+
+ The output is forced to be in block mode. All flow constructs will
+ be converted to block mode.
+
+ - **flow**
+
+ The output is forced to be in flow mode. All block constructs will
+ be converted to flow mode.
+
+ - **flow-oneline**
+
+ The output is forced to be in flow mode, but no newlines will be
+ emitted; the output is going to be a (potentially very) long line.
+
+ - **json**
+
+ The output is forced to be in JSON mode. Note that it is impossible
+ to output an arbitrary YAML file as JSON, so this may fail.
+
+ - **json-oneline**
+
+ The output is forced to be in JSON mode and in a single line.
+
+ - **dejson**
+
+ Output is in block YAML mode but with special care to convert
+ JSON quoted strings in as non-idiomatic YAML as possible.
+ For example `{ foo: "this is a test" }` will be emitted as
+ `foo: this is a test`. YAML can handle scalars without using
+ excessive quoting.
+
+.. option:: -C MODE, --color=MODE
+
+ It is possible to colorize output using ANSI color escape sequences,
+ and the mode can be one of:
+
+ - **off**
+
+ Never colorize output.
+
+ - **on**
+
+ Always colorize output.
+
+ - **auto**
+
+ Automatically colorize output when the output is a terminal.
+ This is the default.
+
+.. option:: -V, --visible
+
+ Make all whitespace (spaces, unicode spaces and linebreaks) visible.
+ Note that this is performed using UTF8 characters so it will not work
+ on non-UTF8 terminals, or a non-UTF8 complete font.
+
+.. option:: -s, --sort
+
+ Sort keys on output. This option is disabled by default.
+
+.. option:: -c, --comment
+
+ Experimental output comments option. Enabled output while preserving comments.
+ Disabled by default.
+
+.. option:: --strip-labels
+
+ Strip labels on output. Disabled by default.
+
+.. option:: --strip-tags
+
+ Strip tags on output. Disabled by default.
+
+.. option:: --strip-doc
+
+ Strip document indicators on output. Disabled by default.
+
+.. rubric:: Tool mode select options
+
+.. option:: --dump
+
+ Select `dump` mode of operation. This is the default.
+ This mode is also enabled when the called binary is aliased to
+ *fy-dump*.
+
+ In this mode, all files provided in the command line will be dumped
+ in one continuous stream, to the standard output, using document start
+ indicators to mark the start of end new file.
+
+ If the file provided is `-` then the input is the standard input.
+
+.. option:: --testsuite
+
+ Select `testsuite` mode of operation.
+ This mode is also enabled when the called binary is aliased to *fy-testsuite*.
+
+ In this mode, a single YAML file is read and an event stream is
+ generated which is the format used for *yaml-testsuite* compliance.
+
+ If the file provided is `-` then the input is the standard input.
+
+.. option:: --filter
+
+ Select `filter` mode of operation.
+ This mode is also enabled when the called binary is aliased to *fy-filter*.
+
+ In this mode, a single YAML file is read from the standard input for each path
+ that is provided in the command line a document will be produced to the
+ standard output.
+ To use file instead of standard input use the `-f/--file` option.
+
+ If the file provided is `-` then the input is the standard input.
+
+ .. option:: -f FILE, --file=FILE
+
+ Use the given file as input instead of standard input.
+
+ If first character of `FILE` is **>** the the input is the content of the option
+ that follows.
+ For example --file ">foo: bar" is as --file file.yaml with file.yaml "foo: bar"
+
+.. option:: --join
+
+ Select `join` mode of operation.
+ This mode is also enabled when the called binary is aliased to *fy-join*.
+
+ In this mode, multiple YAML files are joined into a single document, emitted
+ to the standard output.
+
+ If the file provided is `-` then the input is the standard input.
+
+ .. option:: -T PATH, --to=PATH
+
+ The target path of the join. By default this is the root **/**.
+
+ If first character of `FILE` is **>** the the input is the content of the option
+ that follows.
+
+ .. option:: -F PATH, --from=PATH
+
+ The origin path of the join (for each input). By default this is the root **/**.
+
+ If first character of `FILE` is **>** the the input is the content of the option
+ that follows.
+
+ .. option:: -t PATH, --trim=PATH
+
+ Trim path of the output of the join. By default this is the root **/**.
+
+ If first character of `FILE` is **>** the the input is the content of the option
+ that follows.

+# SYNOPSIS
+#
+# AX_CHECK_ENABLE_DEBUG([enable by default=yes/info/profile/no], [ENABLE DEBUG VARIABLES ...], [DISABLE DEBUG VARIABLES NDEBUG ...], [IS-RELEASE])
+#
+# DESCRIPTION
+#
+# Check for the presence of an --enable-debug option to configure, with
+# the specified default value used when the option is not present. Return
+# the value in the variable $ax_enable_debug.
+#
+# Specifying 'yes' adds '-g -O0' to the compilation flags for all
+# languages. Specifying 'info' adds '-g' to the compilation flags.
+# Specifying 'profile' adds '-g -pg' to the compilation flags and '-pg' to
+# the linking flags. Otherwise, nothing is added.
+#
+# Define the variables listed in the second argument if debug is enabled,
+# defaulting to no variables. Defines the variables listed in the third
+# argument if debug is disabled, defaulting to NDEBUG. All lists of
+# variables should be space-separated.
+#
+# If debug is not enabled, ensure AC_PROG_* will not add debugging flags.
+# Should be invoked prior to any AC_PROG_* compiler checks.
+#
+# IS-RELEASE can be used to change the default to 'no' when making a
+# release. Set IS-RELEASE to 'yes' or 'no' as appropriate. By default, it
+# uses the value of $ax_is_release, so if you are using the AX_IS_RELEASE
+# macro, there is no need to pass this parameter.

+# AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS])

+# AX_APPEND_LINK_FLAGS([FLAG1 FLAG2 ...], [FLAGS-VARIABLE], [EXTRA-FLAGS])
+#
+# DESCRIPTION
+#
+# Check whether the given FLAG works with the current language's
+# preprocessor/compiler/linker, or whether they give an error. (Warnings,
+# however, are ignored.)
+#
+# ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
+# success/failure.
+#
+# If EXTRA-FLAGS is defined, it is added to the current language's default
+# flags (e.g. CFLAGS) when the check is done. The check us thus made
+# with the following flags: "CFLAGS EXTRA-FLAGS FLAG". EXTRA-FLAGS can
+# for example be used to force the compiler to issue an error when a bad
+# flag is given.
+#
+# AX_APPEND_FLAG appends the FLAG to the FLAG-VARIABLE shell variable or
+# the current language's flags if not specified. FLAG is not added to
+# FLAG-VARIABLE if it is already in the shell variable.
+#
+# AX_APPEND_COMPILE_FLAGS checks for each FLAG1, FLAG2, etc. using
+# AX_CHECK_COMPILE_FLAG and if the check is successful the flag is added
+# to the appropriate FLAGS variable with AX_APPEND_FLAG. The
+# FLAGS-VARIABLE and EXTRA-FLAGS arguments are the same as in the other
+# macros. AX_APPEND_LINK_FLAGS does the same for linker flags.
+#
+# NOTE: Based on AX_CHECK_COMPILER_FLAGS and AX_CFLAGS_GCC_OPTION.

+# SYNOPSIS
+#
+# AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
+#
+# DESCRIPTION
+#
+# This macro figures out how to build C programs using POSIX threads. It
+# sets the PTHREAD_LIBS output variable to the threads library and linker
+# flags, and the PTHREAD_CFLAGS output variable to any special C compiler
+# flags that are needed. (The user can also force certain compiler
+# flags/libs to be tested by setting these environment variables.)
+#
+# Also sets PTHREAD_CC to any special C compiler that is needed for
+# multi-threaded programs (defaults to the value of CC otherwise). (This
+# is necessary on AIX to use the special cc_r compiler alias.)
+#
+# NOTE: You are assumed to not only compile your program with these flags,
+# but also link it with them as well. e.g. you should link with
+# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
+#
+# If you are only building threads programs, you may wish to use these
+# variables in your default LIBS, CFLAGS, and CC:
+#

+ * OPEN_MEMSTREAM(3) BSD and Linux Library Functions OPEN_MEMSTREAM(3)
+ *
+ * SYNOPSIS
+ * #include "memstream.h"
+ *
+ * FILE *open_memstream(char **bufp, size_t *sizep);
+ *
+ * DESCRIPTION
+ * The open_memstream() function opens a stream for writing to a buffer.
+ * The buffer is dynamically allocated (as with malloc(3)), and
+ * automatically grows as required. After closing the stream, the caller
+ * should free(3) this buffer.
+ *
+ * When the stream is closed (fclose(3)) or flushed (fflush(3)), the
+ * locations pointed to by bufp and sizep are updated to contain,
+ * respectively, a pointer to the buffer and the current size of the
+ * buffer. These values remain valid only as long as the caller performs
+ * no further output on the stream. If further output is performed, then
+ * the stream must again be flushed before trying to access these
+ * variables.
+ *
+ * A null byte is maintained at the end of the buffer. This byte is not
+ * included in the size value stored at sizep.
+ *
+ * The stream's file position can be changed with fseek(3) or fseeko(3).
+ * Moving the file position past the end of the data already written fills
+ * the intervening space with zeros.
+ *
+ * RETURN VALUE
+ * Upon successful completion open_memstream() returns a FILE pointer.
+ * Otherwise, NULL is returned and errno is set to indicate the error.
+ *
+ * CONFORMING TO
+ * POSIX.1-2008
+ *

+// For others CPU, the compiler will be more cautious, and insert extra code to ensure aligned access is respected.
+// If you know your target CPU supports unaligned memory access, you want to force this option manually to improve performance.
+// You can also enable this parameter if you know your input data will always be aligned (boundaries of 4, for U32).

+// XXH_ACCEPT_NULL_INPUT_POINTER :
+// If the input pointer is a null pointer, xxHash default behavior is to trigger a memory access error, since it is a bad pointer.
+// When this option is enabled, xxHash output for null input pointers will be the same as a null-length input.
+// This option has a very small performance cost (only measurable on small inputs).
+// By default, this option is disabled. To enable it, uncomment below define :
+// #define XXH_ACCEPT_NULL_INPUT_POINTER 1
+
+// XXH_FORCE_NATIVE_FORMAT :
+// By default, xxHash library provides endian-independant Hash values, based on little-endian convention.
+// Results are therefore identical for little-endian and big-endian CPU.
+// This comes at a performance cost for big-endian CPU, since some swapping is required to emulate little-endian format.
+// Should endian-independance be of no importance for your application, you may set the #define below to 1.
+// It will improve speed for Big-endian CPU.

+
+XXH state space must first be allocated, using either static or dynamic method provided above.
+
+Start a new hash by initializing state with a seed, using XXHnn_reset().
+
+Then, feed the hash state by calling XXHnn_update() as many times as necessary.
+Obviously, input must be valid, meaning allocated and read accessible.
+The function returns an error code, with 0 meaning OK, and any other value meaning there is an error.
+
+Finally, you can produce a hash anytime, by using XXHnn_digest().
+This function returns the final nn-bits hash.
+You can nonetheless continue feeding the hash state with more input,
+and therefore get some new hashes, by calling again XXHnn_digest().
+
+When you are done, don't forget to free XXH state space, using typically XXHnn_freeState().
