  19 LilyPond currently only outputs TeX and MIDI.  The pictures and

  21 graphics tools.  The papersize used for these examples is A4.
  22 The  images are in PNG format, and should be viewable with any current browser.
  23 We don't use GIFS due to <a href="http://www.gnu.org/philosophy/gif.html">patent problems</a>.
