I like TuxGuitar a lot (as well as the program icon :-)). The exported pdf
and printed tabs look nice, but they could be improved by making use of
Lilypond (http://lilypond.org/web/). An example of generated staff/tab
can be found on http://lilypond.org/doc/v2.10/Documentation/user/
lilypond/Tablatures-basic.html#Tablatures-basic. Lilypond is open source
and runs on all current platforms.
Are there any plans yet for exporting to or embedding of Lilypond?
Keep up the good work,
