  27   * figure out which set of command line options should make ly2dvi:
  28
  29       na: create tex only?
  30       na: create latex only?
  31       na: create tex and latex
  32       default: create dvi only
  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   * for foo.ly, rename ly2dvi.dir to out-ly2dvi, foo.ly2dvi, foo.dir ?
  41
  42   * move versatile taglines,
  43
  44      \header {
  45         beginfooter=\mutopiaPD
  46         endfooter=\tagline  -> 'lily was here <version>'
  47      }
  48
  49      lilytagline (->lily was here), usertagline, copyright, lily-version
  50      etc.
  51
  52   * head/header tagline/endfooter
  53
  54   * dvi from lilypond .tex output?  This is hairy, because we create dvi
  55     from lilypond .tex *and* header output.
  56
  57   * multiple \score blocks?
  58
  59   * Introduce verbosity levels
