I think this is the right approach.

With regard to the script I have a few comments/suggestions:

It would be nice if the tool could be used to *only* update the
openLilyLib versions without actually running LilyPond. This would be
useful in cases where you usually use editors (like Frescobaldi) to
invoke LilyPond and to create the actual command line to be used. And in
cases where `lilypond` is not the invocation to be used. I'm
specifically talking of my use of Frescobaldi, but I'm sure this holds
for many other users as well.

Maybe it would be cool if ollc could be made accessible as a module too.
That way external tools could integrate it more easily (e.g. have
Frescobaldi call it to set openLilyLib to the right state.
