Hi Stefano,

Excellent response.

>> As you can see ...
Admittedly, I did see the syntax in the example.  What I didn't see,
alas, was the precise option I wanted to use.  By time I clicked my
SciTE editor, thus overlaying the example,  I forgot the syntax.
Remembering the words was all I could muster.  Sad tale :-)

>> OptionParser
Looks good, especially the comprehensive example.

Best wishes,
Richard
