-"""Compile an .idl file to Blink V8 bindings (.h and .cpp files).
-
-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
