Need full example of C extension on Macintosh (CW)

[Louis M. Pecora]

I am homing in on writing a simple C extension on a Macintosh using
CodeWarrior, but, as usual, the nitty gritty details are confounding
me.  I could use a FULL example.  I mean a project, .exp file, AND the
C source files.  In the Python download there are Build examples in the
Mac folder, but they are missing the C source.  Does anyone have the C
source or can point to it on the web for one of these examples, like
AE.prj and AE.prj.exp which are already there, but the source code
(AE.c and AE.h ?) are missing?  Thanks for any help.

BTW, I will be able to provide a detailed example for the FAQ if I ever
get far enough.
