Re: Production Web Applications in Prolog

Hi Lyn,

Yes, my plan is to make a first gitHub-release of the whole thing on
Sunday (since next week and maybe also the week after I won't be able
to work on it). I will announce the release on this list, and, as
always, I'd appreciate feedback of any kind, in particular if it's
constructive. Please don't expect too much - it won't be Pengine 1.0.
But you'll be able to install your own instance of the server, and
write your first Pengine app, and, if you're adventurous, present it
to the rest of the world, but still there will be a lot of polishing
that need to be done.

Best,
Torbjörn
