That's why I didn't like the method, but...

understood.

Anyways, better idea: the shell script is a bootstrap for the  
software - it sets a fixed root path as configured at build time and  
starts another script, the main command shell of the app.  I added a  
test for the env var for when it's started from a Mac app package, so  
it could set the root path dynamically.  I originally did this with  
an OnMyCommand droplet.

Since I already changed the script, I decided to make it Mac-only and  
let the script figure out the root path.  No Mac test needed, no env  
vars needed from the python startup.  The py2app setup will install  
this copy of the startup shell instead of the one from the software.   
Bonus of less to change in the original software source.
