# tocfix - move a DVI file table of contents to its proper position

# TeX puts the table of contents at the end of the DVI file.
# If you're printing multiple pages per sheet, you can't fix it
# on the printout.  This program moves the TOC to be right after
# the titlepage and copyright page.
# It's a safe no-op to run this program on a DVI file more than once.

# Some explanation: the TOC has negative page numbers, represented
# to dviselect by an underscore.  The titlepage and copyright page
# have TeX page numbers 1 and 2, but so do the first two pages of the
# first chapter.  So we have to use absolute, as opposed to TeX,
# page numbers to get them right, represented to dviselect by an
# equals sign.

# This program assumes that the DVI file has the standard Texinfo
# format -- a titlepage, a copyright page, then the real text.
