All,

I realize that this thread is kind of old now, and a lot of work has gone
into making LilyJAZZ work using some fun and fancy Scheme code, but it would
appear that the once practical use of "\jazzOn", etc. should be abandoned in
favor of the work I've done at making LilyJAZZ a fully compatible font? Just
thinking out loud...

BTW, I've tried contacting Torsten again to see if he has a licensing
preference for LilyJAZZ and LilyJAZZText (OFL, GPL, or whatever). Waiting to
hear back now, though based on others' comments, he may be out of reach
since last year.

Regards,
Abraham

P.S. Way to go Torsten! LilyJAZZ is awesome! Can't wait to get your work out
in the LilyPond mainstream! Should be soon :) so stay tuned!
