A dead simple but not very robust solution is

   if arg[0] == 'menu.lua' then

Slightly more robust:

   if arg[0]:match("[.%w]*$") == 'menu.lua' then

Replace "menu.lua" with the name of your file. Still not 100 % robust 
(you could have files named menu.lua in different directories), but 
maybe enough to cover your needs.
