Snippet/template how to use lilypond-book with xelatex

[Till Rettig]

Hi,
I was writing about this already some time ago, now I prepared a small 
file that demonstrates how to use xelatex (and its advanced font 
selection features) whith lilypond-book. This is only a workaround since 
it pretends to lilypond-book to use pdflatex instead. But something like 
this could be nice in the template section of the LM. I only cannot add 
it myself to lsr, because it is not a "lilypond" snippet.
How are the lilypond-book templates handled, are they added also from lsr?

Greetings
Till

Normal \textbf{font} commands inside the \emph{text} work,
because they \textsf{are supported by \LaTeX{} and XeteX.}
If you want to use specific commands like \verb+\XeTeX+, you
should include them again in a \verb+\ifxetex+ environment.
You can use this to print the \ifxetex \XeTeX{} command \else
XeTeX command \fi which is not known to normal \LaTeX .

In normal text you can easily use lilypond commands, like this:

\begin{lilypond}
{a2 b c'8 c' c' c'}
\end{lilypond}

\noindent
and so on.

The fonts of snippets set with lilypond will have to be set from inside 
of the snippet. For this you should read the AU on how to use lilypond-book.

Auch Umlaute funktionieren ohne die \LaTeX -Befehle, wie auch alle anderen
seltsamen Zeichen: ß ČĒŇ, wenn sie von der Schriftart unterstützt werden.
