 """Generate template values for a callback interface.
 
 FIXME: Not currently used in build.
 This is a rewrite of the Perl IDL compiler in Python, but is not complete.
 Once it is complete, we will switch all IDL files over to Python at once.
 Until then, please work on the Perl IDL compiler.
 For details, see bug http://crbug.com/239771
