You want "popen".  For non-windows platforms, "os.popen" is where you 
can find it.  For Win32 systems, you need the win32 extensions, and
"win32pipe.popen".

.........

The commands module has a nice function that runs a program and returns 
the exit status and output as a tuple.

Under Windows NT or Win2k, you can use the PATHEXT environment variable.
Simply add ".py" to the semi-colon sep'd list of extensions, and off you
go!

You can use an option database. If you create a file called optionDB 
with for example the following kind of entries:

*font:                   Times New Roman
*Button*foreground       blue
*foreground              black

You can then apply these via

root.option_readfile('optionDB')
