+
+TLS
+
+If you specify -bind and -tlsbind simultaneously, then you will have
+both raw and encrypted listening sockets. You can use -bind "" to
+disable raw socket.
+
+AUTHENTICATION
+
+You can turn on optional client authentication by preparing passwords
+file and using the -passwords argument. Format of passwords file is:
+
+ login1:password1\n
+ login2:password2\n
+ ...
+
+LOG FILES
+
+Log files are not opened all the time, but only during each message
+saving. That is why you can safely rename them for rotation purposes.
+
+STATE FILES
+
+Each state file has the name equals to room's one. It contains two plain
+text lines: room's topic and room's authentication key (empty if none
+specified). For example:
+
+ % cat states/meinroom
+ This is meinroom's topic
+ secretkey
