% Accented Turkish based on 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.

% Accents added by P. A. MacKay in December, 1986.

% Accents are intended to be exact copies of the accents in the
% Computer Modern file accent.mf, with the following exceptions:
%    1.  Bar accents are adjusted to the width of the associated letter.
%    2.  The hat accent is pinched in to fit the letter i.
%    3.  Acute and grave accents are rotated to whatever angle
%        best suits the letter associated letter.
%    4.  The under_h accent is based on an inverted tie accent.

% No attempt is made to put the accent in the same position
% that it would occupy if \TeX\ put it in with the \accent primitive.
% Each accent has been adjusted for vertical and horizontal position
% position to best fit the associated letter.

% Character codes \0033--\0037, \0053, \0074--\0076, \0176 and \0177
% are generated.
% Character \0040 is generated |iff not monospace|.
