Well this is how I understood the process.

Basically the code is read and exec-ed and the the func_code
func_code.co_varnames are extracted. Then they apply all the clever tricks
to turn the function into a valid Zope method, by (I assume) creating a
Zope method and replacing its func_code and the associated func_defaults
and arguments with the ones extracted from the external function.

The relevant code can be found in
Zope/lib/python/App/Extensions.py and
Zope/lib/python/Products/ExternalMethod/ExternalMethod.py
