-"""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 |
