[Blindmath] LaTex to Nemeth?

Sat Aug 29 22:36:56 UTC 2009

Does anyone  here have samples or can point me in the direction of some
samples in Nemeth braille so that I can work with conversions to and from
LaTeX?

Any help would be appreciated.

Hello,
What I will try and do (I was planning to do this anyway to try and feed 
back to Duxbury systems and see how they respond) is to download the 
latest version (unfortunately I will be stuck with a demo version) and 
see what results I get.

Unfortunately I don't know what version(s) my previous experience was 
with, it was the university who owned the license and so I never had 
direct access to the software being used (they did assure me it was the 
latest version of DBT at the time).
