ngIRCd CVSHEAD
- When the daemon should switch to another user ID (ServerID is defined in
the configuration file) and is not running in a chroot environment, it
changes it's working directory to the home directory of this user. This
should enable the system to write proper core files when not running with
root privileges ...
- Enhanced the "test suite": please have a look at src/testsuite/README!
