Hi folks,

I'm trying to write some documentation for this item in the 2.6 NEWS file:

*******************
Grid lines, vertical lines synchronized with notes, can be drawn across
staves, by adding suitable engravers.
*******************

I want to include this in the 'Educational Uses' section, but I'm having
trouble coming up with something that really works. For example, I'd
like to have two parallel staves with different rhythms, and grid lines
following the beat. I imagine this sort of example could be useful in
all sorts of educational (and analytical) situations.

I started with the example in the NEWS file,
(http://lilypond.org/doc/v2.6/Documentation/topdocs/lily-1269821286.ly)
but any attempts to a) understand it and b) modify it have ended in a mess.

Is there a volunteer with more knowledge than me willing to come up with
a workable solution?

Thanks,

Cameron
