+"""
+    This module offers a small place to start building game clients from.
+
+    You can use this for:
+
+        - Learning how the system works.
+        - Debugging a game server.
+        - Debugging a game that behaves weirdly.
+    
+    This module lets you host a game, let online servers participate in it,
+    and then analyze the outcome.
+
+    
+    You can build several things with this:
+    
+    1. You can build an AI trainer that trains on existing players.
+    2. You can build an ELO evaluator that compares the performance of various
+        strategies.
