   2 # tocfix - move a DVI file table of contents to its proper position
   3
   4 # TeX puts the table of contents at the end of the DVI file.
   5 # If you're printing multiple pages per sheet, you can't fix it
   6 # on the printout.  This program moves the TOC to be right after
   7 # the titlepage and copyright page.
   8 # It's a safe no-op to run this program on a DVI file more than once.
   9
  10 # Some explanation: the TOC has negative page numbers, represented
  11 # to dviselect by an underscore.  The titlepage and copyright page
  12 # have TeX page numbers 1 and 2, but so do the first two pages of the
  13 # first chapter.  So we have to use absolute, as opposed to TeX,
  14 # page numbers to get them right, represented to dviselect by an
  15 # equals sign.
  16
  17 # This program assumes that the DVI file has the standard Texinfo
  18 # format -- a titlepage, a copyright page, then the real text.
