To install, place 'CommandAPI_dummy.jar' into 'forge/mcp/jars/mods' then place the folder 'tlf' into 'forge/mcp/src/minecraft'

To use, instead of putting 'event.registerServerCommand(new yourCommand());' in your 'FMLServerStartingEvent' function, put 'CommandAPI.add[Player/Op]Command(new yourCommand());' in your PreInit, Init, or PostInit method. It doesn't matter which.
