        """${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]]

        """${cmd_name}: Show and modify requests

        [See http://en.opensuse.org/openSUSE:Build_Service_Collaboration
        for information 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.

        usage:
            osc request list [-M] [-U USER] [-s state] [-D DAYS] [-t type] [-B] [PRJ [PKG]]
            osc request log ID
            osc request [show] [-d] [-b] ID

            osc request accept [-m TEXT] ID
            osc request decline [-m TEXT] ID
            osc request revoke [-m TEXT] ID
            osc request wipe ID
            osc request reopen [-m TEXT] ID
            osc request approvenew [-m TEXT] PROJECT

            osc request checkout/co ID
            osc request clone [-m TEXT] ID

            osc review list [-U USER] [-G GROUP] [-s state]
            osc review add [-U USER] [-G GROUP] ID
            osc review accept [-m TEXT] ID
            osc review decline [-m TEXT] ID
            osc review new [-m TEXT] ID            # for setting a temporary comment without changing the state

        You need to call the command inside a package directory, which should be a
        buildsystem checkout. (Local modifications are fine.)

        The arguments REPOSITORY and ARCH can be taken from the first two columns
        of the 'osc repos' output. BUILD_DESCR is either a RPM spec file, or a
        Debian dsc file.

        The command honours packagecachedir, build-root and build-uid
        settings in .oscrc, if present. You may want to set su-wrapper = 'sudo'
        in .oscrc, and configure sudo with option NOPASSWD for /usr/bin/build.

        If neither --clean nor --noinit is given, build will reuse an existing
        build-root again, removing unneeded packages and add missing ones. This
        is usually the fastest option.

        If the package doesn't exist on the server please use the --local-package
        option.
        If the project of the package doesn't exist on the server please use the
        --alternative-project <alternative-project> option:
        Example:
            osc build [OPTS] --alternative-project openSUSE:10.3 standard i586 BUILD_DESCR
