I've installed lilypond and
texlive-context-lilypond-2013.84.svn23167-17.1.7.noarch. However when following
the example in the documentation ("3.1 An example of a musicological
document"), I get an error at the step where pdflatex is called:
---
lilypond-book --output=out --pdf lilybook.lytex
lilypond-book (GNU LilyPond) 2.18.2 
Reading lilybook.lytex...
���lots of stuff deleted���
Compiling lilybook.tex...
cd out
pdflatex lilybook
���lots of stuff deleted���
xpdf lilybook
(replace xpdf by your favorite PDF viewer)
---
The error is "! LaTeX Error: Environment lilypond undefined." where there is
\begin{lilypond}.

The package contains only two files:
> rpm -ql texlive-context-lilypond-2013.84.svn23167-17.1.7.noarch
/usr/share/texmf/tex/context/third/lilypond/t-lilypond.tex
/var/adm/update-scripts/texlive-context-lilypond-2013.84.svn23167-17.1.7-zypper

So it seems the package dos not work at all!

Using "--format texi" (or "htmL" or "docbook") does not produce a texinfo file,
but also a LaTeX file!

Some further experiments showed that lilypond-book doe not replace
\begin{lilypond}...\end\lilypond}pairs, but only source inluded by
\lilypondfile.
