# May 2007: |

# 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 |
