		OPTIONS ($SCRIPT)
		    -i, --init      Initialize the bare repository on the remote.
				-u, --upstream  Set $GIT_SERVER as the remote for the local repo.
		    --name <NAME>   Name of the repository on the remote. By default it
		                    will use the basename of the local repository. This
		                    is also used as the value for cgitrc's repo.name option

		    --section <SEC> Section name for the section for the repository on cgit.
		                    By default, it will be in root section.

		    --desc <DESC>   Description of the repository. If it is set to '-', the
		                    description will be read from stdin. By default, it will
		                    be blank.

		NOTE
		    This was run via the local git-export helper script. The current
		    <GIT_DIR> is used in place of <REPO> argument.
