Understand your feeling.  Can you do the same with 'sed'?  I would be
curios how to get uid created.

Just for fun, I wrote first usable equivalent python text persing script.

See attached.  It is loner than equivalent awk, perl or bash scripts.  It
certaily needs some idioms to get us started.  But extending Python
script seems easier when it get larger ;-)

Took me a while to get this working.  Not bad excersize reading "Lerning
Python".  Does any one have suggestions of better python coding practice?
