* irc.c: IRC-Befehle
*
* $Log: irc.c,v $
+ * Revision 1.68 2002/02/25 17:46:27 alex
+ * - an User wird nun immer ein "komplettes" Prefix verschickt.
+ *
+ * Revision 1.67 2002/02/25 13:21:25 alex
+ * - WHOIS wird nicht mehr automatisch an den "Original-Server" weiterge-
+ * leitet: war eh nicht RFC-konform und machte Probleme mit Clients.
+ *
+ * Revision 1.66 2002/02/23 21:39:48 alex
+ * - IRC-Befehl KILL sowie Kills bei Nick Collsisions implementiert.
+ *
+ * Revision 1.65 2002/02/23 00:03:54 alex
+ * - Ergebnistyp von Conn_GetIdle() und Conn_LastPing() auf "time_t" geaendert.
+ *
+ * Revision 1.64 2002/02/19 20:06:45 alex
+ * - User-Registrierung wird nicht mehr als Nick-Aenderung protokolliert,
+ * - VERSION liefert nun doch wieder den Debug-Status im Reply.
+ *
+ * Revision 1.63 2002/02/19 02:21:17 alex
+ * - der Debug-Level wird bei VERSION nicht mehr geliefert. Grund: a) absolut
+ * unnoetig und b) Compiler-Fehler, wenn ohne Debug-Code configure'd ;-))
+ *
+ * Revision 1.62 2002/02/17 23:38:58 alex
+ * - neuer IRC-Befehl VERSION implementiert: IRC_VERSION().
+ *
+ * Revision 1.61 2002/02/17 19:03:12 alex
+ * - NICK-Aenderungen wurden dem User selber mit dem falschen Prefix geliefert.
+ *
+ * Revision 1.60 2002/02/17 17:43:14 alex
+ * - Fehlerhafte Modes werden nun ausfuehrlicher an den Client gemeldet.
+ *
+ * Revision 1.59 2002/02/17 17:30:21 alex
+ * - NICK-Aenderungen werden an alle Server und betroffene Clients gemeldet.
+ * - Neue Funktion IRC_WriteStrRelatedPrefix().
+ *
* Revision 1.58 2002/02/17 17:18:59 alex
* - NICK korrigiert.
