1.06 [KK 2006-07-25] Small documentation fix. Embedded c-conf upped to
     1.03 (protection from endless recursive directory
     scans). Optimized http_serve() for short messages (no
     piggybacking is necessary after the initial chat). Flag -u (user
     switch) removed; user switching won't work given privileged TCP
     ports, shared memory access and semaphores all mixed together (or
     in other words: I'm too lazy right now to make this work
     elegantly.)
     Version 1.06 promoted to the next stable.
