[Blindmath] Math Conversion Software

[John J. Boyer]

This isn't quite shameless self-promotion. Others are very interested in 
the software I described in my last message.

Mike and others who are interested might like to join the 
liblouis-liblouisxml mailing list or the brailleblaster mailing list. 
Math conversion software is a subject of considerable interest on both.
