From 392f490baec0d20c048d65f4f4046daf8b8a5186 Mon Sep 17 00:00:00 2001 From: goodale Date: Thu, 25 Apr 2002 22:03:52 +0000 Subject: Initial import of new Einstein stuff. This has the new thorns, but not all are fully functional yet. When I have completed this stage I'll send an updated spec out with some questions which have arisen during this process. Please don't import anything new without checking with me first, as I want to play games on the server copying cvs files around to preserve histories on files which are only minimally touched.
