Description: C-based curses widget library (development files) CDK stands for "Curses Development Kit". CDK sits on top of the curses library and provides 21 ready to use widgets for rapid application development of text-based interfaces. CDK delivers many of the common widget types required for a robust interface. Widgets can be combined to create complex widgets if needed. Looks like you could use that and extend it as needed? I am personally not that convinced about the idea of a library specific to blind users, I'd rather have a library which eases ncurses-based UI development (i.e, wraps some of the obscure apsects of ncurses) and which simply has different modes for different sorts of users. A normal mode and a braille mode if you want. Then simply check an enivonment variable at startup for what mode to use, or any other sort of configurability. This way, your userbase will potentially be greater, and therefore you will find and fix more bugs in the implementation. > This library is intended to be used for applications, thatdon't already > have > a textbased interface (synthesizers, sequencers...).

BTW, do you know about midi.el? http://delysid.org/music/midi.el -- CYa, Mario
