- * client.c: Management aller Clients
- *
- * Der Begriff "Client" ist in diesem Fall evtl. etwas verwirrend: Clients sind
- * alle Verbindungen, die im gesamten(!) IRC-Netzwerk bekannt sind. Das sind IRC-
- * Clients (User), andere Server und IRC-Services.
- * Ueber welchen IRC-Server die Verbindung nun tatsaechlich in das Netzwerk her-
- * gestellt wurde, muss der jeweiligen Struktur entnommen werden. Ist es dieser
- * Server gewesen, so existiert eine entsprechende CONNECTION-Struktur.
+ * Client management.
