$PROGNAME: [-BCDhKS] [-c file] [-m dir] [-p dir] [-s dir] [target] [pkgname]

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

 bootstrap-update
  Updates bootstrap packages with latest versions available from registered
  repositories in the XBPS configuration file, by default set to
  <masterdir>/usr/local/etc/xbps/repositories.plist.

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

 build-pkg [pkgname|all]
  Build a binary package from <pkgname> or all packages with the <all>
  keyword. The package(s) must be installed into <destdir> for this to work.

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

 chroot
  Enter to the chroot in <masterdir>.

 clean [pkgname]
  Remove <pkgname> build directory.

 clean-autodeps
  Removes all package dependencies installed automatically.

 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>/builddir.

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

 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 being fully copied.

 list
  List installed packages in <masterdir>.

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

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

 show [pkgname]
  Show information for the specified package.

 show-deps <pkgname> <build|run>
  Show required dependencies for <pkgname>. If <build> is set, only build time
  dependencies are shown, if <run> is set only run time dependencies are shown.

 show-files <pkgname>
  Show package files from <pkgname>. Package must be fully installed
  into <masterdir> for this to work (stowed).

 show-revdeps <pkgname>
  Show reverse dependencies for <pkgname>, i.e packages that are currently
  depending on <pkgname>.

 stow [pkgname]
  Stow <pkgname> files from <destdir> into <masterdir> and register package
  in database. When a package is \`stowed', its files will be available in
  <masterdir>, and other packages will be able to found 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:
 -B  Used in the install target, a binary package is built for any
     required dependency as well as for <pkgname>. The local repository
     pkg-index is created or updated after a successful package installation.
 -C  Do not remove build directory after successful installation.
 -c  Path to global configuration file:
     if not specified ${XBPS_ETCDIR}/xbps-src.conf is used.
 -D  Only install <pkgname> to package's destdir (set to
     <masterdir>/destdir/<pkgname>-<version> by default).
 -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>/host/binpkgs or if XBPS_HOSTDIR is set <hostdir>/binpkgs.
 -S  Overrides and disables XBPS_PREFER_BINPKG_DEPS even if it was
     set in the configuration file xbps-src.conf.
 -s  Source distribution files directory, overwritting default path at
     <masterdir>/host/sources or if XBPS_HOSTDIR is set <hostdir>/sources.
