LaTeX2HTML. This is not safe to do in general (for the reasons LaTeX2HTML protects against dvips to begin with), but is safe if we do not actually need to run dvips. Note that we also assume it is safe if the user specifically requests PostScript generation. See the comments for further explanation.

|
|
--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.
|

--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)
