    HTMLDOC is copyright 1997-2016 by Michael R Sweet and is provided under the
    terms of version 2 of the GNU General Public License.  See the LEGAL STUFF
    section below for details.

    Documentation for HTMLDOC is available in the "doc" subdirectory and is
    generated from HTML "source" files into HTML, PostScript, and PDF using
    HTMLDOC.

    HTMLDOC supports most HTML 3.2 and some HTML 4.0 markup as well as BMP, GIF,
    JPEG, and PNG images.  Eventually HTMLDOC will be compliant with HTML 4.0
    and support CSS.

USING HTMLDOC

    COMPLETE DOCUMENTATION FOR HTMLDOC IS AVAILABLE IN THE "doc" SUBDIRECTORY.
    THE FOLLOWING PROVIDES BASIC INFORMATION ON USING HTMLDOC AT THE
    COMMAND-LINE AND DOES NOT DISCUSS THE GUI OR WEB SERVER FUNCTIONALITY.

    HTMLDOC accepts a list of HTML "source" files and will generate HTML,
    PostScript, or PDF output via command-line options.  A summary of
    command-line options can be shown with the "--help" option:

        htmldoc --help

    HTMLDOC normally expects "structured" documents, with chapters, etc.
    Chapters begin with a <H1> markup and continue to the end of the listed HTML
    files or the next <H1> markup, whichever comes first.  To convert
    unstructured documents such as web pages, use the "--webpage" option to
    HTMLDOC:

        htmldoc --webpage ...

    To generate a Level 2 PostScript file you might use:

        htmldoc -f outfile.ps chapter1.html ... chapterN.html

    Similarly you can generate a PDF file of the same source files using:

        htmldoc -f outfile.pdf chapter1.html ... chapterN.html

    Finally, to generate HTML files for viewing (with a linked table-
    of-contents) do the following:

        htmldoc -t html -d outdir chapter1.html ... chapterN.html

    or:

        htmldoc -t html -f outfile.html chapter1.html ... chapterN.html

    A complete description of all command-line options and HTML guidelines can
    be found in the software users manual in the "doc" directory.


CURRENT LIMITATIONS

    - No support for style sheets.
    - No support for HTML forms.
    - HTML 4.0 table elements and attributes are not supported (background,
      rules, THEAD, TFOOT, etc.)
    - No support for encrypting PDFs with 256-bit AES.


CREDITS

    Many thanks to Leonard Rosenthol for providing changes to support a Mac OS
    version of HTMLDOC.

    The table VALIGN and "HALF PAGE" code was contributed by D. Richard Hipp.

    The multiple header/footer image code was contributed by Lynn Pye.

    The RC4 encryption code is from librc4 1.1 by the folks at Carnegie Mellon
    University.

    The MD5 hash code is from L. Peter Deutsch at Aladdin Enterprises (creators
    of Ghostscript, among other things).


ENCRYPTION SUPPORT

    HTMLDOC includes code to encrypt PDF document files using the RC4 algorithm
    with up to a 128-bit key. While this software and code may be freely used
    and exported under current US laws, other countries may restrict your use
    and possession of this code and software.
