-/*
- * This little program is used to parse the FreeType headers and
- * find the declaration of all public APIs. This is easy, because
- * they all look like the following:
- *
- * FT_EXPORT( return_type )
- * function_name( function arguments );
- *
- * You must pass the list of header files as arguments. Wildcards are
- * accepted if you are using GCC for compilation (and probably by
- * other compilers too).
- *
- * Author: David Turner, 2005, 2006
- *
- * This code is explicitly placed into the public domain.
