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

		Drops a specified package from the official repositories to the Arch
		User Repository.

		This command requires a local Git clone of the package repository. It
		reconfigures the repository for AUR compatibility and pushes it to the
		AUR. Afterwards, the package is removed from the official repository.

		By default, the package is automatically disowned in the AUR.

		OPTIONS
		    --no-disown    Do not disown the package on the AUR
		    -f, --force    Force push to the AUR overwriting the remote repository
		    -h, --help     Show this help text

		EXAMPLES
		    $ ${COMMAND} foo
		    $ ${COMMAND} --no-disown --force
