Targets:
 build <pkg>            Build a package (fetch + extract + configure + build).
 build-pkg [<pkg>|all]  Build a binary package from <pkg>.
                        Package must be installed into destdir. If the <all>
                        keyword is used instead of <pkg>, all packages
                        currently installed will be used.
 chroot                 Enter to the chroot in masterdir.
 configure <pkg>        Configure a package (fetch + extract + configure).
 extract <pkg>          Extract distribution file(s) into build directory.
 fetch <pkg>            Download distribution file(s).
 info <pkg>             Show information about <pkg>.
 install-destdir <pkg>  build + install into destdir.
 install <pkg>          install-destdir + stow.
 list                   List installed packages in masterdir.
 listfiles <pkg>        List installed files from <pkg>.
 remove	<pkg>           Remove package completely (destdir + masterdir).
 stow <pkg>             Copy <pkg> files from destdir into masterdir and
                        register package in database.
 unstow	<pkg>           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.
 -u	Update the checksum in template file if used in 'fetch' target.
