manifest*.
When working with *virtual manifests*, package-related cargo commands, like
-`cargo build`, won't be available anymore. But, most of such commands support
-the `--all` option, will execute the command for all the non-virtual manifest in
-the workspace.
+`cargo build`, default to all packages in the workspace as if `--all` was used.
+This can be changed by passing a `--package` or `-p` command-line parameters.
