$progname: [-CDhKS] [-c <file>] [-m <dir>] [-p <dir>] [-s <dir>] <target> [<pkgname>]

Targets:
 bootstrap
	Build and install from source the bootstrap packages
	into <masterdir>.

 build [pkgname]
	Build package source (fetch + extract + configure + build).

 build-pkg [pkgname|all]
	Build a binary package from <pkgname> or all packages if <all>
	is specified. Package must be installed into destination directory.

 checkvers
	Checks installed package versions in <masterdir>
	against srcpkgs for new available versions.

 chroot
	Enter to the chroot in <masterdir>.

 clean [pkgname]
	Remove <pkgname> build directory.

 configure [pkgname]
	Configure a package (fetch + extract + configure).

 extract [pkgname]
	Extract package source distribution file(s) into the build directory.
	By default set to <masterdir>/pkg-builddir.

 fetch [pkgname]
	Download package source distribution file(s).

 info [pkgname]
	Show information for the specified package.

 install [pkgname]
	Installs a package into destination directory and \`stows' its
	files into <masterdir>. If a package is not from bootstrap group,
	its files will be symlinked rather than copied.

 list
	List installed packages in <masterdir>.

 list-files <pkgname>
	List package files from <pkgname>.

 make-repoidx
	Build a package index for the local repository associated with
	the master directory <masterdir>. By default set to
	<masterdir>/pkg-binpkgs. To specify another repo, use -p <dir>.

 remove [pkgname]
	Remove package completely from <destdir> and <masterdir>.

 stow [pkgname]
	Stow <pkgname> files from <destdir> into <masterdir> and register
	package in database. When a package is \`stown', its files will
	be available in <masterdir>, and other packages will be able to
	depend on it.

 unstow [pkgname]
	Remove <pkgname> files from <masterdir> and unregister package
	from database.

On targets that accept [pkgname], a package name can be specified and xbps-src
will execute the task on any CWD (Current Working Directory). If the argument
is omitted xbps-src assumes that CWD is in the target package. Example:

	$ cd srcpkgs/libX11 && xbps-src install
	$ xbps-src install libX11

Both ways are equivalent.

Options:
 -C     Do not remove build directory after successful installation.
 -c     Path to global configuration file:
        if not specified @@XBPS_INSTALL_ETCDIR@@/xbps-src.conf is used.
 -D     Only install <pkgname> to package's destination directory set
        to <masterdir>/pkg-destdir/<pkgname>-<version>.
 -h	Usage output.
 -K     Do not remove automatic package dependencies while building
        or installing a package with XBPS_PREFER_BINPKG_DEPS enabled.
 -m     Master directory, overwritting the value set in the configuration
        file xbps-src.conf.
 -p     Local packages repository, overwritting default path at
        <masterdir>/pkg-binpkgs.
 -S     Overrides and disables XBPS_PREFER_BINPKG_DEPS even if it was
        set in the configuration file xbps-src.conf.
        it was set in the configuration file.
 -s     Source distribution files directory, overwritting default path at
        <masterdir>/pkg-srcdistdir.
