1. Compares a Packages files and a Sources file This is a program to compare a Packages files and a Sources file to see which programs need (re)compiling for any given architecture. Quinn diff knows about architecture specific packages (e.g. lilo) and can easily exclude them via a Packages-arch-specific file. The output is a list of source packages complete with accurate section and version information, suitable for use in build daemons or just in a script to auto-snarf the necessary source.
