Whoops, I didn't see your previous email.  Ok, to access any system
command or script, you should be able to use the os.system() command:

>>> import os
>>> os.system("ls")
#pico07694#  cs188        exam_template.html  mbox          resume
GNUstep      cs198        exams               messages      rgb00001.pat
# and lots of other files

Any other commands should work as well --- you might need to indicate the

However, Python 2.0, which will be coming out soon, should have a fixed
