--- DESCRIPTION ---------------------------------------------------------------
--
--  This module provides information about builtin entities.
--
--- DOCU ----------------------------------------------------------------------
--
--  language: Haskell 98
--
--  Currently, only builtin type names are supported.  The only builtin type
--  name is `__builtin_va_list', which is a builtin of GNU C.
