I missed in your original post that you only want one consistent 
personal library path abbreviated, leaving everything else alone. So the 
above is not applicable. And a custom excepthook very easy.

How should the traceback mechanism will know what that path is?

To answer the objection about having to search the whole disk when on a 
'foreign' machine, the top line of the traceback could be

Traceback: ... = C:/users/me/pystuff

I never noticed that. Thanks for the exchange of information.
