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
