Hard to really explain all at once.

Was a ton of bots in one (daily chance, fishing bot, slots, etc). Had an integrated plugin API so the bot was able to be ever-extended dynamically if you just wrote a plugin for it in Python. I believe Arti rewrote it a while ago but then stopped working on it (he isn't the original author of the program I believe).

I also think GAME's LG program is derived from it a bit.

Edit: contrary to the name, it actually had nothing to do with mules lol. (no idea why it was named that.)
