        """${cmd_name}: Show meta information, or edit it

        Show or edit build service metadata of type <prj|pkg|prjconf|user|pattern>.

        This command displays metadata on buildservice objects like projects,
        packages, or users. The type of metadata is specified by the word after
        "meta", like e.g. "meta prj".

        prj denotes metadata of a buildservice project.
        prjconf denotes the (build) configuration of a project.
        pkg denotes metadata of a buildservice package.
        user denotes the metadata of a user.
        pattern denotes installation patterns defined for a project.

        To list patterns, use 'osc meta pattern PRJ'. An additional argument
        will be the pattern file to view or edit.

        With the --edit switch, the metadata can be edited. Per default, osc
        opens the program specified by the environmental variable EDITOR with a
        temporary file. Alternatively, content to be saved can be supplied via
        the --file switch. If the argument is '-', input is taken from stdin:
        osc meta prjconf home:user | sed ... | osc meta prjconf home:user -F -

        When trying to edit a non-existing resource, it is created implicitly.


        Examples:
            osc meta prj PRJ
            osc meta pkg PRJ PKG
            osc meta pkg PRJ PKG -e

            osc meta <prj|pkg|prjconf|user|pattern> ARGS...

        "log" will show the history of the given ID

        "show" will show the request itself, and generate a diff for review, if
        used with the --diff option.

        "decline" will change the request state to "declined" and append a
        message that you specify with the --message option.

        "wipe" will permanently delete a request.

        "revoke" will set the request state to "revoked" and append a
        message that you specify with the --message option.

        "accept" will change the request state to "accepted" and will trigger
        the actual submit process. That would normally be a server-side copy of
        the source package to the target package.

        This command is mostly used internally by the 'build' subcommand.
        It needs to be called from within a package directory.

        The BUILD_DESCR argument is optional. BUILD_DESCR is a local RPM specfile
        or Debian "dsc" file. If specified, it is sent to the server, and the
        buildinfo will be based on it. If the argument is not supplied, the
        buildinfo is derived from the specfile which is currently on the source
        repository server.

        The returned data is XML and contains a list of the packages used in
        building, their source, and the expanded BuildRequires.

        The arguments PLATFORM and ARCH can be taken from the first two columns
        of the 'osc repos' output.
