[Edu-sig] Starting Python

[Winston Wolff]

Hello André-

90% of the program is the user interface.  The actually running of  
the program is just spawning a Python process.  I do a little bit of  
magic to allow multi-file programs that I discuss below, but  
basically it's just popen().  Regarding the "stop" button, that is  
just killing the process.  And the ">>>" button, is just adding the  
command line option to Python:
	-i     : inspect interactively after running script

Regarding the magic I do before running a script, if there exits a  
file named main.py in the current or parent folder, then that is run  
instead of the current script.  And the first argument on the command  
line is the current script's file name.  This allows me to write  
multi-file programs, but it also allows me to do funny things like  
pre-load certain libraries and add them to __built_in__ or to execute  
the user's script in a testing framework which I do for a tutorial.   
I haven't made these things ready for release due to time, but having  
the main.py file that can "override" the execution of these scripts  
turned out to be very handy.
