Hi Urs and Abraham,
thanks for your replies. I already assumed that this is mostly not new
to you, but I didn't know which parts of it.

Ok, fair enough. As you are aware and see it the same way, I am happy :)

No (see below), about a custom font.

Yes, that's true, that works as all stylesheets are present.

That's ok, but I would argue that this is too complicated if
\useNotationFont MyFont
could also work out-of-the box.

Yes there is! Abraham was so kind to produce me a variant of Emmentaler
with a more Cadence-like clef. But also in general I think it should
work for any font present in the lilypond folder.

Yes. I missed the “Fix no-brace-available bug” commit.

Ok.

I prefer option c) letting the shell expand the expression and accept a
list of directories (I don't know how the expansion works in Windows,
though).
More comments on this script:
What is the minimum python version you want to support?
A help message (-h) would be nice -> how about using argparse? (Not
necessary for this low amount of options though.)
> Yes, I'd be happy to see a pull request
I come up with one branching from the current master.

Yes, I also did not intend to remove the separate downloads.
tl;dr: The only really open issue (3) is the handling of this line:
\useNotationFont SomeFontUnknownToOLL
Cheers,
Joram
