%D This module serves to include LilyPond music directly in the

%D
%D It is supposed to work only with LilyPond's stable version 2.10.
%D
%D LilyPond 2.11 (and therefore probably 2.12) changed the output parameter.

%D only one face per font file etc.

%D \type{\startlilypond} is a multistage implementation, because

\type{\startlilypond} accepts options, as in\crlf

It is also possible to mix text and music:
\lower 8.2pt\hbox{\lilypond[fragment=true,staffsize=16,time=no]{g'}} is a g.

(Seems like this still doesn't work...)

TODO: The \type{\lower} in the example above should not be necessary.
