I didn't know about the $(git ls-files) trick.  Previously, I'd
only "grep foo *", and try whichever directories seemed relevant.

Neat!

Err... are you saying "you should not do that!", or "why on earth
would you want to do that, you idiot?", or "are you so lacking in
technical ability that you can't figure out how to do this
yourself?"  ?

- I possess the technical ability to do this.
- I'm asking if it's a good idea.

Last I heard, John wanted to produce the website from the
stable/x.y branch.  Of course, you could still ask if
STABLE_VERSION != VERSION... I just figured that if I was going to
extent /VERSION, I might as well add one more variable (i.e. the
SATBLE_ or DEVEL_, whichever was not strictly necessary) just to
make it easier to keep that info in sync between master and
stable/x.y,

Yes.  We could still use those, but
- it require an active internet connection to build lilypond
  (at least the first time).  This seems like a Bad Idea (tm).
- those scripts would need a bit of rewriting
- once rewritten, they'd add another bit to the complexity of the
  build system.
