% This is the University of Washington collection of |mode_defs|
% together with the macros to provide font-wide specials describing the
% |mode_def| that is used for each generated font, and the Xerox-world
% comments in the tfm file.  If a "?" is typed as the first response
% to the "*" prompt after this or a derived base file is loaded,
% a list of all current |mode_def|s will be given.
%
% This file follows a convention that has emerged in the discussion
% of |mode_def|s in TUGboat.  
%    1.  The print engine is identified wherever possible, rather than
%        the printer which incorporates that print-engine.
%    2.  Because |mode_def| names may not contain digits, each digit is
%        given its full name, as in RicohFourZeroEightZero.
%
% WARNING: Some of the modes have never actually been tested
