Hi Andrew

That would be great. Upgrade to python3 only? Or python2 + python3?
Consider that GUB might not be able to build lilypond anymore until its 
python is upgraded.  There's already a problem, see here:
https://github.com/gperciva/gub/pull/6#issuecomment-431063463

So your work might be kept on hold until GUB is fixed and/or a new 
build system is set up. I have the feeling that the latter might be 
less difficult.
