Hello Everyone,

For several years I have been working on two braille transcription
libraries with the support of ViewPlus Technologies. One, liblouis, is a
braille translator and back-translator. The other, liblouisxml,
translates xml documents into properly formatted braille, using liblouis
to do the translation. It will handle MathML, text and, eventually,
graphics, chemistry and music. ViewPlus is using both libraries in its
TSS software. Despite the support of a for-profit company, the software
is Open Source and Free. liblouis is also being used by Serotech, Design
Sciences, HandyTech and Orca. 

I have started a mailing list for those who are interested in 
to or just following the development of this software. To join, send a 
message to
liblouis-liblouisxml-request at
and put subscribe in the subject line.

To learn more about the software and to download it, go to . There is a project for liblouis on and a Mac application that works nicely with VoiceOver. The 
above site has links to both of these. The liblouisxml package includes 
programs for translating xml files to braille, backtranslatiog to text 
or html, reformatting braille files, and handling poorly formatted text. 
These programs run at the command line on most Unix-like systems, 
including linux, FreeBSD and Mac OS X.
