    --  9/28/00 - RLB - Added some style sheets.
    --		- RLB - Updated to use absolute positioning for paragraph

    --			with it.
    --  4/10/03 - RLB - Updated to add access to search pages (not generated
    --			here; make them by hand, it only needs to be done once).

    --  4/11/03 - RLB - Changed some formats to meet WC3 validation requirements.
    --  9/09/04 - RLB - Removed unused junk noted by Stephen Leake.

    --  1/19/06 - RLB - Added code so that only styles that are used are
    --		        included in the result (this decreases the minimum
    --			file size by a lot).
    --  1/21/06 - RLB - Specified leading for Swiss example styles, because

    --			changes.
    --		- RLB - Added code so that spaces after an opening tag
    --			and before a closing tag are converted to non-breaking.
    --  3/28/06 - RLB - Removed unnecessary space from headers.
    --  3/30/06 - RLB - Added a bit of space around inline pictures.

    -- 10/25/11 - RLB - Added old insertion version to Revised_Clause_Header.
    --  2/15/12 - RLB - Removed horizontal rules from page breaks in HTML;

    --  3/26/13 - RLB - Added Script_HTML.
    --  2/ 8/16 - RLB - Added styles for the Ada-Auth.org header.
    --		      - Defined change colors for versions 5 and 6. (Actually
    --			"borrowed" the color for version 2, so the new colors
    --			are for version 2 and 6. Can't use dark blue, as links
    --			are that color.)
    --  3/ 3/16 - RLB - The color change is hell on the RR manuals. Redid
    --			it to switch the colors only if version 5 is in use.
    --  4/20/16 - RLB - Slightly increased the base indent as a lot of
    --			paragraph numbers are overlapping.
    --		      - Added Force_New_Revision_Colors.
