Write a custom backend?

[Mathieu Demange]

Hello all,

Could anybody help me to know if writing a custom output backend (in scheme, of course) for Lilypond is something doable? I mean without modifying any of Lilypond's internals.

I believe the output backend principle is a good sign of extensibility but is it really the case? How to instruct Lilypond to use a custom one, then?

Thanks for your help.

Cheers,

Mathieu
