Revision 2.1 - (show annotations) (download)
Fri Dec 3 22:08:01 2004 UTC (20 years ago) by kusanagi
Branch: MAIN
Changes since 2.0: +5 -10 lines
Finally added a real group of Exception classes
Re-strucuted all the log systems (for better performances on unpacking)
Minor changes following the packets changes
