% Accented Turkish based on Computer Modern Roman upper 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.

% Upper case letters with accents above are all given the height
% value |body_height|, with the result that the accents kern up
% into the white space or leading from the previous line.  It is
% the responsibility of the formatter to set TeX's baselineskip
% so that there is adequate room for such accents.  The cup on
% upper case G is probably the most extreme case in serifed roman
% or italic fonts; the hat on O is the most extreme in sans-serif
% fonts

% Character codes \0013--\0017, \0044--\0046, \0052 and \0136--\0137 
% are generated.
