Converter from HTML into indexed HTML, PostScript, or PDF
Description
HTMLDOC converts HTML source files into indexed HTML, PostScript, or
Portable Document Format (PDF) files that can be viewed online or
printed. With no options a HTML document is produced on stdout.
The second form of HTMLDOC reads HTML source from stdin, which allows
you to use HTMLDOC as a filter.
The third form of HTMLDOC launches a graphical interface that allows
you to change options and generate documents interactively.
