+"""A simple Multi-User Dungeon (MUD) game. Players can talk to each
+other, examine their surroundings and move between rooms.
+
+Some ideas for things to try adding:
+    * More rooms to explore
+    * An 'emote' command e.g. 'emote laughs out loud' -> 'Mark laughs
+        out loud'
+    * A 'whisper' command for talking to individual players
+    * A 'shout' command for yelling to players in all rooms
+    * Items to look at in rooms e.g. 'look fireplace' -> 'You see a

+    * Items to pick up e.g. 'take rock' -> 'You pick up the rock'
+    * Monsters to fight
