In the documentation, snippets created with @lilypond[verbatim] are now syntax-highlighted using the Pygments library. This is implemented through an internal option in lilypond-book. In HTML, a CSS stylesheet is generated by Pygments and the output uses tags with classes. In PDF, the @setcolor{} command is used inside @example environments. Info does not support colors.

Because Pygments' support for LilyPond is recent, the library is vendored in a ZIP archive. The intent is to keep it so until the next release has percolated in GNU/Linux distributions we care about.

Closes #1005 (closed)
