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

		Star a package's GitLab project.

		If no package is specified, the current directory's package will be used.
		Multiple packages can be specified to star multiple projects at once.

		Every usage of the star command must be authenticated. Consult the
		'pkgctl auth' command to authenticate with GitLab or view the
		authentication status.

		OPTIONS
		    -h, --help     Show this help text
		    -u, --unstar   Remove star from the project instead

		EXAMPLES
		    $ ${COMMAND} pacman
		    $ ${COMMAND} --unstar pacman
		    $ ${COMMAND} libfoo libbar
