/*
* README
* This plugin makes use of the GameQ library to be able to query many different
* types of game servers and display the results in munin. You can see a list of
* supported games at http://gameq.sourceforge.net/#games
*
* This plugin has 2 environment variables:
* game_config_file - Defaults to /etc/munin/munin-game.ini. The location of the config file
* game_state_file - Defaults to /var/lib/munin/plugin-state/game. The location of the munin state directory
*
* (Probably) FAQ
* Q: Why PHP?
* A: The GameQ library is written in PHP, so it was either that or rewrite the entire library.
*
* Q: Why have you used a config file instead of environment variables?
* A: Way too much to fit data inside an environment variable unfortunately. Imagine
* trying to fit information about 50 servers all inside one variable.
*
* Q: I want to ask you a question!
* A: I'm on most IRC networks under the nick Azelphur, or email me. support@azelphur.com
*
* Q: It's not working!
* A: Try running ./game autoconf, it'll probably tell you what's up.
