The LilyPond web site (http://lilypond.org/website/) and the documentation
(e.g. http://lilypond.org/doc/v2.12/Documentation/user/lilypond/index.html)
both have alternate style sheets, which means that we have 4 more style
sheets to maintain than we really need. Does anyone actually use them? And
if you do, would it be a serious problem if they were got rid of? Please
shout if you need them to be kept, letting us know what use you put them to.
