+% Include file for LilyPond.
+%
+% This file defines various macros to acommodate lilypond output.
+%
+% It should run with plain TeX, LaTeX, pdftex, and texinfo.
+%
+% To avoid interferences, lilyponddefs.tex should be loaded within a group.
+% To load it only once, most of the definitions must be global.
+%
+% The overall structure of a file created by LilyPond is as follows:
+%
+% <lilypond parameter definitions>
+% \ifx\lilypondstart \undefined
+% \input lilyponddefs
+% \fi
+% \lilypondstart
+% <font setup and note output>
+% \lilypondend
+%
+% No footers and headers are provided for the stand-alone run (i.e., for
+% directly saying `latex <LilyPond output>'.
+%
+%
+% Avoid \par while reading this file.
