disable rendering of a section of music

[Matthew Peltzer]

I'm fairly certain I've seen this in the user docs or on this list,
but I can't seem to find out how to temporialy disable lilypond from
rendering a section of music (so as to focus on a smaller section by
hiding sections that are finished & to increase compilation times).

I remember it was *something* like:

#if 0
%lots of music
#endif
%buggy music being worked on


...but I can't figure out the exact syntax
