Probably easier to write a tool that combs directly through LiveCode 
objects.

   Those who dream by night in the dusty recesses of their minds
   wake in the day to find that all was vanity; but the dreamers
   of the day are dangerous men, for they may act their dream
   with open eyes, and make it possible.
