5 # Changes:
6 # May 2007:
7 # Made bsfix make one pass for all things and add some glocal targets for
8 # setting up the whole thing. Contributed by kiorky
9 # (kiorky@cryptelium.net).
10 # December 2006:
11 # I pretty much rewrote the logic of the bsfix functions
12 # and xml-rewrite.py because they were so slow
