[Request/Bounty] Tablature bends

[Marc Hohl]

Hello all,

after about half a year I have to admit that I don't have a) the time
and b) the programming skills to implement bends in lilypond[1]. Sorry.

Bends are important for guitarists, so I offer 75$ for this issue and
I am posting to the tablature list, because perhaps someone else there
is willing to donate some money too, to get this task done.

During winter 2009/2010, Carl and I discussed the syntax and implementation
details very intensively in about a dozen mails or so, and as things got
nailed down, I wrote a roadmap how the bend engraver and the tab note head
engraver have to be built/extended. There is also a file bend.ly
which uses slurs to mimic bends - the graphic routines for bends are 
already there,
so I offer my help providing and explaining the roadmap. A skilled developer
should have no problems to code the new engraver and transform the 
graphic routines
into c++ code.

During the bend.ly story, I got in touch with developers of tuxguitar, 
so I think
the whole bend story will make lilypond more attractive as a front end to
tuxguitar users and of course to professional music typesetters working 
on contemporary
guitar music.

Greetings

Marc

[1] It was really hard for me to accept b), but to be honest, I still 
struggle
with some basic concepts of c++ in combination with lilypond, which is 
*very*
frustrating.
