    oh, absolutely... every piece of that thing comes from somebody 
(about six somebodies to be exact) what makes it unique is that its 
compressed, in the right order (I think), and 'without' extraneous 
gibberish that confuses the whole dang thing.

    Its obvious until you get to the @charater.  In fact its taken so 
obviously by *everyone* that no one actually gets it explained without 
eight pages or twelve steps of something until its all confused.

Yes, because depending on your interface the code can get mangled (the 
indentation thing breaks).  the quoted paste seems to avoid this mostly 
with the downside that the quote characters need to be striped from the 
py file.   <sorry>   by the way, any suggestions are welcome regarding 
that too...  there doesn't really seem to be a good way to share code on 
the group consistently.
