% geabbr.gr or geabbr.tex, the 7-bit, TeX version
% July 1994 version, Yiannis N. Moschovakis
% Following the coding of the cl family of fonts

% Ported to UNIX 25-Mar-95, Giorgos Efthivoulidis

% macros for classical Greek under greektex
% with single commands for the accent combinations
% assuming direct entry from the keyboard of 
% the accents, the aspiration marks, 
% the diaeresis and the iota subscript
%
% New features in this version:
%
% The only active characters are high bit, exactly those
% which code the accent combinations
% "Robust" commands for the active characters
% Active characters work before all printable characters
% and commands which expand to begin with a printable character
% They produce unpredictable results before other commands
