$progname: [-Ch] [-c <config_file>] [-m <masterdir>] [-p <pkgdir>] <target>

Targets:
 bootstrap        Build and install the bootstrap packages into <masterdir>.
 build            Build a package (fetch + extract + configure + build).
 build-pkg [all]  Build a binary package from <pkg>.
                  Package must be installed into destdir. If the <all>
                  keyword is used all packages currently installed in
		  <masterdir>/<destdir> will be used.
 checkvers        Checks installed package versions against srcpkgs
                  for new available versions.
 chroot           Enter to the chroot in <masterdir>.
 clean            Remove <pkg> build directory.
 configure        Configure a package (fetch + extract + configure).
 extract          Extract distribution file(s) into build directory.
                  Build directory is always available in
		  <masterdir>/pkg-builddir/<pkg>.
 fetch            Download distribution file(s).
 info             Show information for current pkg build template.
 install-destdir  build + install into destdir.
 install          install-destdir + stow.
 list             List installed packages in <masterdir>.
 listfiles        List installed files from <pkg>.
 make-repoidx     Build a package index for the local repository associated
                  with the master directory <masterdir> or <pkgdir>,
		  or updates it.
 remove           Remove package completely (destdir + masterdir).
 stow             Stow <pkg> files from <destdir> into <masterdir> and
                  register package in database.
 unstow           Remove <pkg> files from <masterdir> and unregister
                  package from database.

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.
 -h	Usage output.
 -m     Master directory, overwritting the value set in the configuration
        file at @@XBPS_INSTALL_ETCDIR@@/xbps-src.conf.
 -p     Package directory, overwritting default path at
        <masterdir>/pkg-binpkgs.
