readme.txt

I have to hold up my hands and confess that I thought I had uploaded the Readme.txt. I apologise to everyone for making you hunt down euclid.py and figuring out how to play the "game".

Thanks also to everyone who took the trouble to comment, as it was very encouraging. Over the last couple of days I've made a lot of progress with the level geometry and will soon be in a position to upload something a bit more robust. I'm still working on this, at least when time permits. I'm having fun, and hopefully the source code might save people a bit of time.

It certainly makes a refreshing change from hacking XML in Python, which is currently a large part of my day job.
