  29       na: create tex only?
  30       na: create latex only?
  31       na: create tex and latex

  33       na: create tex, latex and dvi
  34       -P: create dvi and ps
  35       -p: create pdf
  36       na: * create ps only
  37
  38      etc.
  39
  40   * move versatile taglines,
  41
  42      \header {
  43         beginfooter=\mutopiaPD
  44         endfooter=\tagline  -> 'lily was here <version>'

  46
  47      lilytagline (->lily was here), usertagline, copyright, lily-version
  48      etc.
  49
  50   * head/header tagline/endfooter
  51
  52   * dvi from lilypond .tex output?  This is hairy, because we create dvi
  53     from lilypond .tex *and* header output.
  54
  55   * multiple \score blocks?
  56
  57   * Introduce verbosity levels
