% Computer Modern italic lower case with dotted diacriticals for Turkish etc.
% These letters were originally coded by D. E. Knuth in November, 1979,
% inspired by the Monotype faces used in {\sl The Art of Computer Programming}.

% Sans serif designs by Richard Southall were added in April, 1982.
% The programs were revised for the new \MF\ conventions in 1985.

% Dotted diacriticals added by P. A. MacKay, January, 1987.
