Not at all.  For those of you joining our program, Hector is having a
problem with embedded scheme in lilypond files on Windows NT...

Hmm.  Lilypond requires guile, which is the scheme interpreter which is
"embedded" in the lilypond program.  That's the part which is supposed to
interpret the line which croaks.  I didn't know that guile was even
available for Windows NT, so there may be a problem there.

Does anyone else on the list have any experience with using Lilypond on
Windows NT?
