        """${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 attribute PRJ [PKG [SUBPACKAGE]] [--attribute ATTRIBUTE] [--create|--delete|--set [value_list]]

        Usage:

        on this topic.]

        This command shows and modifies existing requests. To create new requests
        you need to call one of the following:
          osc submitrequest
          osc deleterequest
          osc changedevelrequest
        To send low level requests to the buildservice API, use:
          osc api

        This command has the following sub commands:

        "list" lists open requests attached to a project or package or person.
        Uses the project/package of the current directory if none of
        -M, -U USER, project/package are given.

        "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. The keyword show can be omitted if the ID is numeric.

        "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.

        "checkout" will checkout the request's source package. This only works for "submit" requests.
