"""
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.
