Basically this seems to require command line options, right?j
If so, just include a standard snippet in the __main__ section
of your scripts which checks the first command line option to
see if it's "--jon's_special_pdb_magic" (or whatever ;-) ) and
then programmatically invoke the excepthook stuff...
