Re: Extra staves

[Mats Bengtsson]

I have added your example to the Tips and Tricks document
(i.e. to the input/test/ directory) in the CVS of the development
version.

You can already find a number of examples in the Tips and Tricks section
that involve defining new contexts. If you do a grep for "accepts" or
"alias" in input/test/* or /input/regression/*, you will find them.

Also, I forgot to mention that the best place to learn more about these
aspects is to read the engraver-init.ly. Of course, this is also briefly
described in the manual, see
http://lilypond.org/doc/v2.0/Documentation/user/out-www/lilypond/Defining-new-contexts.html#Defining
and the other sections of same chapter.
