Hi Urs, hi Abraham,

don't worry, it'll end up in LilyPond at some point.  But I have to 
admit that I did not have a look at Abraham's work other than skimming 
over the newest PDFs.  I was travelling, and also will be on vacation 
from Sunday for a week.  As soon as I'm back again, I will push myself 
to polish up and see how we can integrate our work.

By the way, Abraham: IIRC, you asked about how to prepare a patch for 
review.  I'm not an expert in that, but it looks like I did so 
successfully; so if you can wait for another 10 days or so, feel free to 
contact me and I'll do what is necessary.  Or take the offer by other 
friendly helpers.

That's good to hear.  I'm not familiar enough with convert-ly, but I 
agree that if we come up with a somewhat sane approach for choosing the 
fonts, it should not be too hard to concoct a rule which will do the job.

+1.  It's on my TODO list.  I consider this as syntactic sugar over the 
current make-pango-font-tree and make-expert-font-tree, but I totally 
agree that this should be integrated.  Won't be difficult, I just need 
to figure out how to modify the currently active font tree in place.

Ditto.


Best,
