Hi,
Some time ago, I heard of a fantastic GSoC project aimed at enabling
cross-staff spanners.

ice-spanners/
However, this is not yet in any release.
For the score I'm engraving, it would be tremendously helpful to get
this working. I tried to compile the gsoc-2016-spanners branch from
[2]https://github.com/starrynte/lilypond but it didn't do the trick.
I
know this will be unstable, but still, is there a patch somewhere
that
I could apply to use this feature nevertheless?
Thank you very much!
Regards,
Jean Abou Samra
