It'd be very nice if users of this version could run the scripts as the
documentation says; as many potential users certainly come from Windows
(as I did in the past with Cygwin...), it's better they don't have a
"crippled package". It seems to me that doing these improvements:
1) add a notice saying that Python is required (or at least
2) set up the environment variables during installation: add <LilyPond
installation directory>\usr\bin\ to PATH, and add extensions .PY
and .PYC to PATHEXT,
3) compile the C midi lib required by midi2ly into the package.
could be done quite easily by the Windows-native packager.
