Re: [Generateds-users] QUANTICSOFT: I need your help

[Dave Kuhlman]

Nicolas,

Thanks for these kind words.  And, I appreciate the feed-back.

I would love a trip to France.

But, I returned, just this month, from a wonderful and fascinating
2-week trip with family to Spain.  Although I was hoping for a
little more excitement -- Catalonia was threatening to succeed while
we were there, but that did not happen.  I was even able to see
Velásquez's "Las Minenas" at the Museo del Prado.  Ah ha!  So, that
is what reflexivity and recursion are about, I mean in addition to
what they mean for programming languages.

So, France and Nantes may have to wait a little while.

Wait, ... [doing a Web search] ... Yes!  There is a craft beer
revolution going on in France, even though, according to this
article, France has been making good beers for a lot longer than we
have in the U.S.A, likely longer than there has been a U.S.A.

Wow.  Great wine *and* good beer.  I've got to come up with a reason
to visit.  I'll let you know when I do.  I'd love a chance to learn
more from someone who has used generateDS.py and why and how they
use it.

Of course, let me know when and if you have another issue with or
suggestion for generateDS.py.

Dave
