Invoking lilypond-book

A minimal LaTeX file contains these four lines.

   \documentclass[10pt]{article}
   \begin{document}
   hello!
   \end{document}

A minimal lilypond-book file contains these seven lines.

   \documentclass[10pt]{article}
   \begin{document}
   hello!
   \begin{lilypond}
      \new Staff { c'4 }
   \end{lilypond}
   \end{document}

The lilypond context inserts in .tex documents directly.

Process lilypond-book docs like this.

   lilypond-book --pdf --output=out test.tex
   cd out
   pdflatex test.tex
   open test.pdf

Invoking lilypond-book with the --pdf option tells lilypond-book to generate a postprocessed version of test.tex named test.tex together with a number of helper files necessary to create some final .pdf.

Note that invoking lilypond-book with the --pdf option does not tell lilypond-book to create a .pdf directly; further processing with pdflatex is still required.
