%
% The style file is intended to use Izhitsa font.

% The command \<size>Slav (<size>=twl,elv,ten,nin,egt..) loads izhitsa
%    at a definite size. It works both in Plain TeX and LaTeX.
% The command \Slav loads izhitsa font at size of the outer text.
%    It works with LaTeX only. The scheme applied supposes that 
%    the font \<size>rmsl is invoked when roman in the outer 
%    text is set by \<size>rm. 
% If the message "SLAV STYLE: font ... not found" appears,
%   the below list of fonts should be augmented.
%
% The usage of the commands looks like the following
%   ...{\Slav abc {\small abc} abc {\tenSlav abc} abc}...
%
% Both \<size>Slav and \Slav make a number of useful definition 
%   (\titlo, \title, \ttl, accents and special symbols), which are
%   local within the group containing \[size]Slav.
