Fred Drake cfef0096f9 Job.build_html(): When formatting HTML into more than one HTML page, and
not doing the \label{foo} --> foo.html transformation (--numeric was
    specified on the command line), still look to see if there is an
    "About this document..." node and copy that to "about.html", since the
    page footers use that as the target.

"""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)
