Revision: 1.18
Committed: Fri Feb 23 17:51:07 2001 UTC (23 years, 2 months ago) by pjm2
Branch: MAIN
Changes since 1.17: +11 -11 lines
Log Message:
Configuration is now read from the INI file.
This only needs to specify the hostname and port number of the FilterManager, as the
FilterManager itself is responsible for providing the remaining configuration details.
