Thanks, I'll do that, the thought crossed my mind, but I couldn't
decide whether to be a memory tightwad or not, you make a good point.

How do I do that?
foo = os.system("..")?

Honestly, me neither, more than anything I wanted to get a feel for
them, basically I was bound and determined to create a class, but when I
was done, it was obviously stupid.  Unfortunately, most of the stuff I
do is "straight through shell scripty" so, hopefully I can figure out
some decent way to use the OO features of python for that.
