Daemon for automatically building Debian binary packages from Debian sources
The sbuild suite of programs (buildd and sbuild) are used to build binary packages from source packages. The wanna-build database tracks packages which require building; buildd schedules work from information it gets from the wanna-build database; sbuild does the actual package building. . buildd is a daemon which will build Debian packages automatically using the wanna-build database to identify which packages need to be built. Note that the wanna-build database is not packaged, and requires installing separately.
