framer is a tool to generate boilerplate code for C extension types. The boilerplate is generated from a specification object written in Python. The specification uses the class statement to describe the extension module and any extension types it contains. From the specification, framer can generate all the boilerplate C code, including function definitions, argument handling code, and type objects.
