 """Generate 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
