        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:poeml | sed ... | osc meta prjconf home:poeml -F -

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


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

        [See http://en.opensuse.org/Build_Service/Collaboration for information
        on this topic.]

        For "create", there are two ways to use it. Either with a working copy
        or without. If called with no arguments, osc will guess what to submit 
        where. If you don't have a working copy, you can give the respective
        arguments on the commandline (see below for an example).
        Then, the DESTPAC name is optional; the source packages' name will be
        used if DESTPAC is omitted.
        With --message, a message can be attached.
        With --revision, a revision MD5 of a package can be specified which is
        to be submitted. The default is to request submission of the currently
        checked in revision.

        "list" lists open requests attached to a project or package.

        "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.

        "delete" will permanently delete a request and append a
        message that you specify with the --message option.

        "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.

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

        The arguments PLATFORM and ARCH can be taken from 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 and build-root 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

        usage: 
            osc build [OPTS] PLATFORM ARCH BUILD_DESCR
