I could use a refresher on how PJE's patch solves Andy's problem.

I'm not sure if you're asking about how you would execute a zip file after the patch has been applied, or about the mechanics of how the patch works. PJE's last post covered the former question, so I'll cover the gist of the latter.

The patch works by passing the script argument to the import machinery to see if it is recognised as a valid sys.path entry (i.e. either a directory or a zip file in a default Python installation). If it is, then add that location to the front of sys.path and use the -m switch support to execute the "main" module directly.

If the filename passed in isn't recognised as a sys.path entry, then it is executed as a script as normal.

Cheers, Nick.
