Mikubot-2/otouto/plugins/calc.lua
topkecleon b7c81c464f otouto v3.12
Minor changes across the board. More planned. I also may have accidentally screwed with access
permissions (so looks like every file is marked modified).
Moved drua-tg.lua into the otouto/ directory.
Added pokego-calculator.lua plugin (similar to pidgeycalc.com).
