Subject: [PATCH] Added a few new rules that do some search and replacing using
 sed. AFAIK all our build platforms should have sed support (it is built into
 Jambase at least.) I use these rules to do some code generation in my soon to
 be committed MarkAs Tracker add-ons.

This works pretty nifty if I do say so myself.
