engraver how-to?

I am still working on bends for guitar notation. For the moment, I redefined the slur stencil to get the desired results, but this has some severe drawbacks, so this is
only a crude workaround for testing the postscript routines.

A cleaner solution will need a new engraver for this purpose, but I haven't any experience in c++ (at the university, I had lessons in c, but this was in the last millenium, so ...). Therefore, I need some help: where should I look in lilypond's sources
to get an idea of how engravers are defined and integrated in lilypond?

As bends are used to combine two different notes, an approach similar to slurs will be the best (in my opinion), but by randomly picking up any file concerning slurs and ending with .cc isn't the right way to find out how it works (that's what I found out so far).

I think there are some c++ guys at the tablature list, but probably the are very busy with some other things (at least all my calls for help went to /dev/null), so I'm afraid I have to do it
myself *sigh*.

Thanks in advance!
