 # The bot setup is to build stable, unstable, and beta packages for the current

 # be one of these. This build file also has targets for trunk and possibly asan
 # installers.

 # TODO it would be much nicer to have a build variable so the bot can tell us
 # what the current build should be, so we only have to make one .deb/.rpm pair.
