This raised a smile. You are now in broadly the same place I was a few 
years ago.

MM tried to save me some effort by saying he'd already broken AOB's 
stuff. He hadn't kept hold of the break, so although of course I 
believed him I decided to try to break it for myself, which I did in 
full view of sci.crypt. But... I haven't bothered to keep hold of the break.

And then along came you. When you break AOB's stuff, keep hold of the 
break. :-)
