% tex4ht-sage.cfg
%
% Supplies info for jsmath version to tex4ht command line and preamble
%   2009/01/28  Modified to build sage worksheets, dropped font info
%   2010/02/20  Significant improvements, many from Robert Marik
%
% Call as   htlatex <tex-source-file> "tex4ht-sage.cfg" " -cunihtf -utf8"
%   Implements environments of the sagetex package
%   Wraps contents of these environments with the
%   tags <sage>,</sage> as markers.
%   Then a script converts contents to
%   SAGE worksheet cell format
%   CSS additions to fine-tune jsMath spacing
%       suggested by David Cervone (jsMath author)
%
% Managing unicode fonts
% ----------------------
%   To restore minus symbol '-' from its translation to &#x2212;
%   use method described in
%   http://www.cse.ohio-state.edu/~gurari/docs/tug-07/tug07-10.xht
%   i.e. copy the hypertext font encoding file
%   texmf/tex4ht/ht-fonts/mozilla/charset/unicode.4hf to the work
%   directory and add the following record to the file:
%   '&#x2212;' '' '-' ''
%
%   To restore "'" from its translation to &#x2019; search the same file 
%   unicode.4htf for line begining with '&#x2019;' and replace by 
%   +&#x2019;+ ++ +'+ ++
%   with this setting the word "don't" remains as is and not "don&#x2019;t"
