% Computer Modern Roman lower case:
% 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.

% Character codes \0141 through \0172 are generated.
