Just found this very handy info:

its a method of automating the creation of MacOS X pkgs, so it could be done on the SourceForge compile farm's OS X machine automatically. I definitely plan on giving this a shot, but anyone is welcome to give it a shot. I'd love to have the .debs and .rpms scripted as well.
