        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 -

        For meta prj and prjconf updates optional commit messages can be applied with --message.

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


        Examples:
            osc meta prj PRJ
            osc meta pkg PRJ PKG

        The 'request' 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"

        "reopen" will set the request back to new or review.

        "setincident" will direct "maintenance" requests into specific incidents

        "supersede" will supersede one request with another existing one.

        "revoke" will set the request state to "revoked"

        "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 ("submit" requests only).

        "priorize" change the prioritity of a request to either "critical", "important", "moderate" or "low"


        The 'review' command has the following sub commands:

        "list" lists open requests that need to be reviewed by the
        specified user or group

        "add" adds a person or group as reviewer to a request

        "accept" mark the review positive

        "decline" mark the review negative. A negative review will
        decline the request.

        """${cmd_name}: Build a package on your local machine

        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

        usage:
            osc build [OPTS] REPOSITORY ARCH BUILD_DESCR
            osc build [OPTS] REPOSITORY ARCH
            osc build [OPTS] REPOSITORY (ARCH = hostarch, BUILD_DESCR is detected automatically)
            osc build [OPTS] ARCH (REPOSITORY = build_repository (config option), BUILD_DESCR is detected automatically)

            osc build [OPTS] (REPOSITORY = build_repository (config option), ARCH = hostarch, BUILD_DESCR is detected automatically)

        # OSC_SU_WRAPPER overrides the setting of su-wrapper.

        The tool looks up the default responsible person for a certain project or package.
        When using with an OBS 2.4 (or later) server it is doing the lookup for
        a given binary according to the server side configuration of default owners.

        The tool is also looking into devel packages and supports to fallback to the project
        in case a package has no defined maintainer.

        Please use "osc meta pkg" in case you need to know the definition in a specific container.

        PRJ and PKG default to current working-copy path.
