 rough English transliteration of the Greek word for architect. We feel it's a
 good name and hope to live up to the expectations that such a name gives!
 
+An interesting postscript to this story arose with a certain Mr. Ries van Twisk,
+who is the author of another QCad fork called LibreCAD, arrived on the scene.
+For some time Mr. van Twisk had access to the author's private repository and
+rather than work with the author, he decided to create his own fork "from
+scratch". Of course this was burdened with all of the problems that surrounded
+the original QCad CE source done with Qt3 and the porting to Qt4 and the
+Qt3Support module. And so, stagnation reared its ugly head once more. Sad, but
+true.
+
+And so, in light of this prospect, and after the author of Architektonas having
+beat his head against the illogical class structure and general brain-deadness
+of the code, he decided it would be for the best to divorce himself from the
+QCad codebase he so painstakingly ported to Qt4 and start from scratch. The
+result, in our opinion, was worth the effort--and even the porting effort of
+QCad CE was not in vain as it helped the author to clarify that vision and
+arrive at something *much* better. We think you'll agree! And if you don't, we'd
+love to hear from you so that we can improve!
