Amazing indeed. Maybe he needed software for his own projects but found
what's available to be somewhat disappointing. Since he's a programmer
also,
he decided to create his own software and had the generous spirit to give
it
to anyone else who has similar needs. Of course that's only a guess. I'm
grateful such altruistic people are still out there!!!
