scripts/auxiliar/ is well-suited to that sort of thing, but there
hasn't been agreement on including helpers like that in the sources
(with the maintenance promise it entails). Is it a large script?
If so, it needs some consideration. If not, can it fit in an @example
somewhere in the CG? That might also make it more visible.

I'm using Emacs, but prefer 'git grep' for this task (or just opening
the right source file directly: ly:something-do-whatever is usually
in lily/something-scheme.cc, ly:something-interface::calc-foo in
lily/something-interface.cc, etc.). Is there anyone out there who
would use this?

Not that I'm aware of, but then, I have "only" been around on this
list for about two years.


Best,
