"""usage: %(program)s [options...] file ...
Options specifying formats to build:
--html HyperText Markup Language (default)
--pdf Portable Document Format
--ps PostScript
--dvi 'DeVice Indepentent' format from TeX
--text ASCII text (requires lynx)
More than one output format may be specified, or --all.
HTML options:
--address, -a Specify an address for page footers.
--link Specify the number of levels to include on each page.
--split, -s Specify a section level for page splitting, default: %(max_split_depth)s.
--iconserver, -i Specify location of icons (default: ../).
--image-type Specify the image type to use in HTML output;
values: gif (default), png.
--numeric Don't rename the HTML files; just keep node#.html for
the filenames.
--style Specify the CSS file to use for the output (filename,
not a URL).
--up-link URL to a parent document.
--up-title Title of a parent document.
Other options:
--a4 Format for A4 paper.
--letter Format for US letter paper (the default).
--help, -H Show this text.
--logging, -l Log stdout and stderr to a file (*.how).
--debugging, -D Echo commands as they are executed.
--keep, -k Keep temporary files around.
--quiet, -q Do not print command output to stdout.
(stderr is also lost, sorry; see *.how for errors)

# 'dvips_safe' is a weird option. It is used mostly to make
# LaTeX2HTML not try to be too smart about protecting the user
# from a bad version of dvips -- some versions would core dump if
# the path to the source DVI contained a dot, and it's appearantly
# difficult to determine if the version available has that bug.
# This option gets set when PostScript output is requested
# (because we're going to run dvips regardless, and we'll either
# know it succeeds before LaTeX2HTML is run, or we'll have
# detected the failure and bailed), or the user asserts that it's
# safe from the command line.
#
# So, why does LaTeX2HTML think it appropriate to protect the user
# from a dvips that's only potentially going to core dump? Only
# because they want to avoid doing a lot of work just to have to
# bail later with no useful intermediates. Unfortunately, they
# bail *before* they know whether dvips will be needed at all.
# I've gone around the bush a few times with the LaTeX2HTML
# developers over whether this is appropriate behavior, and they
# don't seem interested in changing their position.
