%               Loading Hebrew fonts.                      %
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% 
% Revisions by Yaniv:
% * Scaling factor specified with \magstep<number>, instead of inline
%   expansion of the magnification ratio. It looks nicer this way.
% * \magstephalf fonts where scaled 1100 instead of the (correct) 1095.
%   solved by the previous change.
% * lines broken (probably e-mail problem) on size definitions fixed.
% * Yael's changing of \Huge\ds to magstep4 eliminated.

%
% \tohebrew and \toenglish are called each time the vertical direction
% changes. The do all that is necessary beside changing the direction.
% Currently their task is to change the definition of \rm \bf \it \tt to
% the English or Hebrew version, and disable hyphenation in Hebrew. They
% should not normally be called by users, use \sethebrew \unsethebrew
% \L{} \R{} \embox{} and \hmbox{} to change language.
%
% Changes by Yaniv:
% * Set \hyphenpenalty=\@MM to avoid hyphenation in Hebrew.
%   Remove this when there is a hyphenation file for Hebrew.
%   Keeping two kinds of hyphenation information for English and for Hebrew
%   with the same TeX is something that remains to be solved by the great
%   masters of TeX. (currently intractable)
% * Set \binoppenalty=\@MM and \relpenalty=\@MM so TeX never breaks
%   formulas within Hebrew text.

%   Bilingual Table of Contents and List of Figures       %
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% 1) Section headings are typeset with the default global direction
% 2) Text in section headings in the reverse language should
%    have a protection for the reflection command, as in:
%      \protect\L{English Text}
% 3) Table of contents and list of figures should be typeset with
%    the \starttoc{toc} and \starttoc{lof} commands.
% 4) The table of contents and list of figures will be typeset in
%    main direction in effect where the above commands are placed.
% (The changes needed for the above to work can be found in a
%  previous section of this file)
%
%%%%% Bilingual table of contents and list of figures.
% Support for printing the table of contents and list of figures
% twice, one in Hebrew and once in English was added (required for
% thesis submitted to the Technion). To achieve this do the following:
%
% 1) Use the \bxxx version of the sectioning commands in the text
%    instead of the \xxx version (xxx is one of: chapter section
%    subsection subsubsection caption).
% 2) Syntax of the \bxxx command is \bxxx{Hebrew text}{English text}.
%    Both arguments are typeset in proper direction by default (no need to
%    change direction for the text inside). To use English text in the
%    Hebrew text or vice versa see section 2) above.
% 3) The section header inside the document will be typeset in the
%    global direction in effect at the time. i.e. The {Hebrew text} will
%    be typeset if \sethebrew is in effect and {English Text} otherwise
% 4) The table of contents an list of figures should be included in
%    the text with the \starttoc{toc} and \starttoc{lof} commands.
%    These tables will be typeset in the Hebrew version if \sethebrew
%    is in effect in the place where \starttoc is typeset, otherwise they
%    will be typeset in English.
% 5) LaTeX rewrites the \jobname.toc and \jobname.lof
%    after the \starttoc is typeset and creates new ones. To typeset
%    a table twice within the same document, either run LaTeX on your job
%    once and then add the command \nofiles to the preamble 
%    and run it again, or create
%    new copies of the \jobname.toc and \jobname.lof, say \jobname.eoc and
%    \jobname.eof and use \starttoc{eoc} and \starttoc{eof} for the second
%    version of the tables.
