doc -- Generate and/or validate documentation

    sak doc ?format? ?module...?

        Convert the documentation for the specified module into the
        given format. Modules can be specified by their plain name, or
        as relative path.

	The special format 'validate' causes the tool to syntax check
        of the input without generating actual output. When output is
        generated it is written into the sub-directory 'doc'/format of
        the current working directory.

	The special format 'imake' scans the checkout for manpages and
	saves the list of found files into a file in the support
	directory. This files will be put into CVS. The special format
	'ishow' will dump the contents of this list to stdout. Both
	have been added to make it easy to verify that a checkout has
	all manpages it should have. These two formats ignore any
	module information they are given.

	The format is actually a glob and output is generated for all
	known formats matching it. It is implicitly padded with a * to
	allow the use of prefixes.

        The known output formats (beyond 'validate') are

        - dvi     See latex, + conversion to dvi (via 'latex' application)
        - html    HTML pages
