Add debugger files with luarocks?

[iandol]

Mobdebug can be easily installed using luarocks: https://github.com/pkulchenko/MobDebug -- but for your extension we have to manually move the luapanda.lua file around. It would be nicer if we could just install luapanda alongside luasocket using luarocks. Then the extension and debugger would just work with needing to manually move files around.
