Good stuff, looking forward to using it! I've attached a matching
rebuild-gcj-db2 script and a sample Hello World .spec so that others can
more easily try it out.

Is it worth merging the .db files into one .db file per package, to
reduce the number of files that have to be merged at RPM install time?
