2498     --take: Take package for building [default operation]
2499     -f, --failed: Record in database that a build failed due to

2503         correctly and were uploaded.
2504     -n, --no-build: Record in the database that the packages aren't
2505         desired for this architecture and shouldn't appear in listings even

2520     -o, --override: Override another user's lock on a package, i.e.
2521         take it over; a notice mail will be sent to the other user
