lilypond-book no output

[Rune Zedeler]

I would like an option to lilypond-book that simply removes all the 
lilypond blocks from latex (instead of inserting music). The reason is 
that all the word-counting-tools for dvi-files that I know get really 
confused about the music; so when counting the size of a file (without 
music), one would do

lilypond-book -noinclude blablabla ; latex blabla

and then run the word-counter on the resulting dvi-file.


I have tried to do

\newenvironment{lilypond}
{ \begin{comment} }
{ \end{comment} }

in the start of the lytex-file, which SHOULD just remove the 
lilypond-blocks if the file was processed directly through latex - but 
in fact it does not work (produce an error).
