I may do this if I feel that I can add my improvements
properly.

Yes, this is what I had in mind if I had to implement
the drawing myself (I did this for a chess option),
but I was really hoping to take your parser piece and
combine it with someone else's drawing piece so that
it would be easier!

My goal would be to make the graphic chord boxes small
enough so that they could be put inline above with the
lyrics the way that the current chord letters are put
(some books do this,) instead of just at the top.

Anyway, it might be a while since I am currently
working on my ascii2abctab conversion script (see the
other guitar tabalature thread,) but if someone has
any pointers to (libre) software that can already do
the drawing for me, that might be a little sooner. :)

Thanks,

-Martin
