An extended undefined variable checker for Lua 5.1 using bytecode analysis based on David Manura's globalplus.lua http://lua-users.org/wiki/DetectingUndefinedVariables
-- globalsplus.lua
-- Like globals.lua in Lua 5.1.4 -- globalsplus.lua
-- Like globals.lua in Lua 5.1.4 but records fields in global tables too.
-- Probably works but not well tested. Could be extended even further.

-- usage: lua globalsplus.lua example.lua
