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

		Remove packages from pacman repositories. By default passing a pkgbase removes
		all split packages, debug packages as well as entries from the state repo for
		all existing architectures.

		Beware when using the --partial option, as it may most likely lead to
		undesired effects by leaving debug packages behind as well as dangling entries
		in the state repository.

		OPTIONS
		    -a, --arch    Remove only one specific architecture (disables auto-detection)
		    --partial     Remove only partial pkgnames from a split package. This leaves
		                  debug packages behind and pkgbase entries in the state repo.
		    -h, --help    Show this help text

		EXAMPLES
		    $ ${COMMAND} core-testing libfoo libbar
		    $ ${COMMAND} --arch x86_64 core libyay
