		Usage: ${COMMAND} [OPTIONS] [PKGBASE]...

		Clone Git packaging repositories from the canonical namespace.

		The configure command is subsequently invoked to synchronize the distro
		specs and makepkg.conf settings. The unprivileged option can be used
		for cloning packaging repositories without SSH access using read-only
		HTTPS.

		OPTIONS
		    -m, --maintainer=NAME  Clone all packages of the named maintainer
		    --switch VERSION       Switch the current working tree to a specified version
		    --universe             Clone all existing packages, useful for cache warming
		    -h, --help             Show this help text

		EXAMPLES
		    $ ${COMMAND} libfoo linux libbar
		    $ ${COMMAND} --maintainer mynickname
		    $ ${COMMAND} --switch 1:1.0-2 libfoo
