% LaTeX2HTML Version 2K.1 : html.sty
% 
% This file contains definitions of LaTeX commands which are
% processed in a special way by the translator. 
% For example, there are commands for embedding external hypertext links,
% for cross-references between documents or for including raw HTML.
% This file includes the comments.sty file v2.0 by Victor Eijkhout
% In most cases these commands do nothing when processed by LaTeX.
%
% Place this file in a directory accessible to LaTeX (i.e., somewhere
% in the TEXINPUTS path.)
%
% NOTE: This file works with LaTeX 2.09 or (the newer) LaTeX2e.
%       If you only have LaTeX 2.09, some complex LaTeX2HTML features
%       like support for segmented documents are not available.

% Changes:
% See the change log at end of file.


% Exit if the style file is already loaded
% (suggested by Lee Shombert <las@potomac.wash.inmet.com>
\ifx \htmlstyloaded\relax \endinput\else\let\htmlstyloaded\relax\fi

%%% LINKS TO EXTERNAL DOCUMENTS

% This can be used to provide links to arbitrary documents.

%%% HTMLIMAGE
% This command can be used inside any environment that is converted

% is really a string of options separated by commas ie 
% [scale=<scale factor>],[external],[thumbnail=<reduction factor>
% The scale option allows control over the size of the final image.
% The ``external'' option will cause the image not to be inlined 
% (images are inlined by default). External images will be accessible
% via a hypertext link. 
% The ``thumbnail'' option will cause a small inlined image to be 
% placed in the caption. The size of the thumbnail depends on the
% reduction factor. The use of the ``thumbnail'' option implies
% the ``external'' option.
%
% Example:
% \htmlimage{scale=1.5,external,thumbnail=0.2}
% will cause a small thumbnail image 1/5th of the original size to be
% placed in the final document, pointing to an external image 1.5
% times bigger than the original.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% based upon Eijkhout's  comment.sty v2.0
% with modifications to avoid conflicts with later versions
% of this package, should a user be requiring it.
%	Ross Moore,  10 March 1999
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% Comment.sty   version 2.0, 19 June 1992
% selectively in/exclude pieces of text: the user can define new
% comment versions, and each is controlled separately.
% This style can be used with plain TeX or LaTeX, and probably
% most other packages too.
%
% Examples of use in LaTeX and TeX follow \endinput
%
% Author
%    Victor Eijkhout

%    University Tennessee at Knoxville
%    104 Ayres Hall
%    Knoxville, TN 37996
%    USA
%
%    eijkhout@cs.utk.edu
%
% Usage: all text included in between
%    \comment ... \endcomment
% or \begin{comment} ... \end{comment}
% is discarded. The closing command should appear on a line
% of its own. No starting spaces, nothing after it.
% This environment should work with arbitrary amounts
% of comment.
%
% Other 'comment' environments are defined by
% and are selected/deselected with
% \includecomment{versiona}
% \excludecoment{versionb}
%
% These environments are used as
% \versiona ... \endversiona
% or \begin{versiona} ... \end{versiona}
% with the closing command again on a line of its own.
%
% Basic approach:
% to comment something out, scoop up  every line in verbatim mode
% as macro argument, then throw it away.
% For inclusions, both the opening and closing comands
% are defined as noop
%
% Changed \next to \html@next to prevent clashes with other sty files
% (mike@emn.fr)
% Changed \html@next to \htmlnext so the \makeatletter and
% \makeatother commands could be removed (they were causing other
% style files - changebar.sty - to crash) (nikos@cbl.leeds.ac.uk)

% $Log: html.sty,v $
% Revision 1.39  2001/10/01 22:47:06  RRM
%  --  somehow revision 1.39 was not committed earlier
%  --  it allows a * version of \tableofcontents (used with frames) to be
%      treated as un-starred by LaTeX
%
% Revision 1.39  2000/09/10 12:23:20  RRM
%  --  added *-argument for \tableofcontents  in frames.perl
%      LaTeX should just ignore it
%
% Revision 1.38  1999/07/19 13:23:20  RRM
%  --  compatibility with pdflatex and hyperref.sty
%  	citations are not complete yet, I think
%  --  ensure that \thechapter remains undefined; some packages use it
%  	as a test for the type of documentclass being used.
%
% Revision 1.37  1999/03/12 07:02:38  RRM
%  --  change macro name from \addTOCsection to \htmladdTOClink

%  	file for the external document, for cross-references
%
% Revision 1.36  1999/03/10 05:46:00  RRM
%  --  extended the code for compatibilty with comment.sty

%  	with the excluded material spanning headers and several cells

%  	thanks to Steffen Klupsch and Uli Wortmann for this idea.
%
% Revision 1.35  1999/03/08 11:16:16  RRM

%
%  --  ensure that html.sty can be loaded *after* hyperref.sty
%  --  support new command  \htmlclear for <BR> in HTML, ignored by LaTeX
%  --  ensure {part} and {chapter} counters are defined, even if not used

%  --  get LaTeX to print the revision number when loading
%
% Revision 1.27  1998/06/20 15:13:10  RRM
%  --  \TeX is already protected in recent versions of LaTeX
% 	so \DeclareRobust doesn't work --- causes looping
%  --  \part and \subparagraph need not be defined in some styles
%
