The debug configuration setting should certainly be mentioned in the liblouisutdml documentation. So should a lot of other things. I've done a little work on the documentation recently, but I feel that I must concentrate on design and coding. I'll be glad to collaborate with anyone wheo has experience in documentation. The liblouis documentation also needs work. In addition, we need a BrailleBlaster manual. The preferences.cfg file in the liblouisutdml repository contains all possibloe configuration settings and is intended as a base for documentation. Thanks, John -- John J.
