%		   KD Classical Greek Family of Fonts
%		   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
%
%	A set of MF source fonts for use with TeX version 3.0 or higher
%	accompanied with macros and hyphenation tables to facilitate
%	the typesetting of greek texts
%
%	This piece of work is partially based on original work of
%	Sylvio Levi (design of an excellent set of fonts)  
%	and Yianni Haralambous (ideas about macros other fonts).
