* $Log: ngircd.c,v $
+ * Revision 1.29 2002/03/06 15:36:04 alex
+ * - stderr wird nun in eine Datei umgelenkt (ngircd.err). Wenn der Server
+ * nicht im Debug-Modus laeuft, so wird diese bei Programmende geloescht.
+ *
+ * Revision 1.28 2002/02/27 23:24:29 alex
+ * - ueberfluessige Init- und Exit-Funktionen entfernt.
+ *
+ * Revision 1.27 2002/02/25 11:42:47 alex
+ * - wenn ein System sigaction() nicht kennt, so wird nun signal() verwendet.
+ *
+ * Revision 1.26 2002/02/23 19:06:47 alex
+ * - fuer SIGCHLD wird nun auch SA_NOCLDWAIT gesetzt, wenn vorhanden.
+ *
+ * Revision 1.25 2002/02/19 20:30:47 alex
+ * - SA_RESTART wird fuer Signale nur noch gesetzt, wenn es definiert ist.
+ *
+ * Revision 1.24 2002/02/19 20:08:24 alex
+ * - "Passive-Mode" implementiert: kein Auto-Conect zu anderen Servern.
+ * - NGIRCd_DebugLevel wird (fuer VERSION-Befehl) ermittelt.
+ *
+ * Revision 1.23 2002/02/17 23:40:21 alex
+ * - neue Funktion NGIRCd_VersionAddition(). NGIRCd_Version() aufgespaltet.
+ *
+ * Revision 1.22 2002/01/22 17:15:39 alex
+ * - die Fehlermeldung "interrupted system call" sollte nicht mehr auftreten.
+ *
* Revision 1.21 2002/01/21 00:02:11 alex
* - Hilfetexte korrigiert und ergaenzt (Sniffer).
