2693 Usage: $prgname <options...> <package_version...>
2694 Options:
2695     -v, --verbose: Verbose execution.
2696     --take: Take package for building [default operation]
2697     -f, --failed: Record in database that a build failed due to
2698         deficiencies in the package (that aren't fixable without a new
2699         source version).
2700     -u, --uploaded: Record in the database that the packages build
2701         correctly and were uploaded.
2702     -n, --no-build: Record in the database that the packages aren't
2703         desired for this architecture and shouldn't appear in listings even
2704         if they're out of date.
2705     --dep-wait: Record in the database that the packages are waiting
2706         for some source dependencies to become available
2707     --binNMU num: Schedule a re-build of the package with unchanged source, but
2708          a new version number (source-version + "+b<num>")
2709     --give-back: Mark a package as ready to build that is in state Building,
2710          Built or Build-Attempted. To give back a package in state Failed, use
2711          --override. This command will actually put the package in state
2712          BD-Uninstallable, until the installability of its Build-Dependencies
2713          were verified. This happens at each call of --merge-all, usually
2714          every 15 minutes.
2715     --merge-quinn: Merge quinn-diff output into database.
2716     --merge-packages: Merge Packages files into database.
2717     --pretend-avail: Pretend that given packages are available now and give
2718         free packages waiting for them
2719     -i SRC_PKG, --info SRC_PKG: Show information for source package
2720     -l STATE, --list=STATE: List all packages in state STATE; can be
2721         combined with -U to restrict to a specific user; STATE can
2722         also be 'all'
2723     -m MESSAGE, --message=MESSAGE: Give reason why package failed or
2724         source dependency list
2725         (used with -f, --dep-wait, and --binNMU)
2726     -o, --override: Override another user's lock on a package, i.e.
2727         take it over; a notice mail will be sent to the other user
2728     -U USER, --user=USER: select user name for which listings should
2729         apply, if not given all users are listed.
2730         if -l is missing, set user name to be entered in db; usually
2731         automatically choosen
2732     --import FILE: Import database from a ASCII file FILE
2733     --export FILE: Export database to a ASCII file FILE
2734     --lock-for PID: Locks the database for the process with this pid
2735     --unlock-for PID: Unlocks the database for the process with this pid
2736     --act-on-behalf-of PID: Ignores the lock (if it is held by this pid)
2737     --start-transaction: Creates a copy of the state of the database, for
2738         use with --transactional. This overrides any previous uncommited
2739         transaction. Should only be used after --lock-for
2740     --commit-transaction: Atomically moves the copy back to the main, thus
2741         commiting the changes
2742     --transactional: Flag to indicate that we want to work on the copy
2743
2744 The remaining arguments (depending on operation) usually start with
2745 "name_version", the trailer is ignored. This allows to pass the names
2746 of .dsc files, for which file name completion can be used.
2747 --merge-packages and --merge-quinn take Package/quin--diff file names
2748 on the command line or read stdin. --list needs nothing more on the
2749 command line. --info takes source package names (without version).
