+ * - Channel- und Nicknames werden nun ordentlich validiert.
+ *
+ * Revision 1.16 2002/02/27 23:23:53 alex
+ * - Includes fuer einige Header bereinigt.
+ *
+ * Revision 1.15 2002/02/27 20:32:10 alex
+ * - neue Funktionen Channel_Topic() und Channel_SetTopic().

+ * - neue Funktion Channel_IsMemberOf() implementiert.
+ *
+ * Revision 1.13 2002/02/11 01:00:12 alex
+ * - neue Funktionen Channel_ModeAdd(), Channel_ModeDel(), Channel_UserModes(),
+ * Channel_UserModeAdd(), Channel_UserModeDel().
+ * - Modes in CL2CHAN-Struktur werden nun korrekt initialisiert.
+ *
+ * Revision 1.12 2002/02/06 16:48:48 alex
+ * - neue Funktion Channel_Modes() und Channel_IsValidName().
+ * - Channel-Namen werden (besser) validiert.
+ *
+ * Revision 1.11 2002/01/29 00:11:10 alex
+ * - neue Funktionen Channel_FirstChannelOf() und Channel_NextChannelOf().
