I have been revising sly to use a tab separator in the body of the 
program, such as it is, because it would be more foolproof to have a 
single character for a field separator, but to edit the sly file the 
"space|" is better.  No?  How not?

Processing the output to .ly is simply a matter of running ly-include
with a % on lines where you don't want the includes read in, right now. 
Python probably couldn't find the problem lines anyway.  I will put
the readin feature in the sly script.  I've already been doing it
using lilypond-book.

But bear in mind that the \include method permits one to 
bring up a new version with lilypond only processing the
new part.  For a single long piece, this is much faster.
And it's nice to have lilypond give you a line number that
is the same as the measure number when a mistake is made.
Generating both is the way to go.  It will be done.   DaveA
