pkzip and using popen on Windows 98 ???

[Mark Butterworth - U-Net]

Im having trouble using os.system or popen (both win32pipe & os) under
windows 98.  It will not return the exit value of the command Im running
(which is infozips - zip).  Also when attempting to use win32pipe.popen3 -
my pipe read's hang after one or two reads.

Also does anyone know of any python modules which can read / write pkzip (or
infozip) format files as I don't like calling external commands.

Any help would be appreciated?
