As promised, I've emulated all of the ctypes functionality that I've 
used for potool.  Here's the latest version (it is the same, except it 
does not depend on ctypes):

The ptypes module I've written is rather interesting.  I'd like to 
improve on it (to accommodate variable length arrays, particularly 
those based on structures as in mach-o headers.  and also certain types 
that change based upon "typecodes" in the structure) mapping, and also 
to optimize it a bit (have structures and arrays turn a list of 
non-Indeterminate Packables into a single pack or unpack statement).  
Aside from that, I should change the interface and provide convenience 
methods for the functions that otool and install_name_tool perform.  
The ptypes module is a cute little example of what __metaclass__ can do 
for you.
