In this case I don't see that you need to call multiple programs
simultaneously. You call 'wrenv.exe', then when and if it completes
successfully you call 'make clean'. Calling multiple programs
sequentially should be straightforward. What, specifically, is going
Python's subprocess module rocks on Unix, and provides some useful
corresponding features that are easily available on MS Windows. If
your job is to rock on Windows, don't commit to modules devoted to
rockin' on Unix. Python has multiple ways to run "wrenv.exe", then
"make clean". In particular, check out os.system.
