2525     --take: Take package for building [default operation]
2526     -f, --failed: Record in database that a build failed due to

2560 of .dsc files, for which file name completion can be used.
2561 --merge-packages and --merge-quinn take Package/quin--diff file names
2562 on the command line or read stdin. --list needs nothing more on the
