* Launch the PythonSlave.py script.

* This works exactly as if you'd double clicked on the file in the Finder, which
|
||
|
|
* not surprisingly is how its implemented (via the AppleEvents route of course).
|
||
|
|
*
|

|
|
* Largely based on code submitted by Mark Roseman <roseman@cpsc.ucalgary.ca>
