mod_muc_dicebot: A thing to roll dice Do you see what happens, Jitsi? Do you see what happens when you make it hard for me to use a proper bot? This is what happens, Jitsi. This is what happens when you meet a stranger in the alps! Ahem. In all seriousness, this is more of a quick hack than anything else. It will look for `.r` in MUC messages and if it finds it, it'll interpret it as an instruction to roll a few dice. Injects the results in the body of the message. Eats the message alive if it is malformed.
