% Purpose:	grmode.sty is a latex include file used in conjuctio with
% the grlatex package (format lgreek, and files lgreek.tex, 
% grfonts.tex, greek.sty)
% This file switches grlatex to a global greek mode. A latin mode is defined
% to access the original latex mode. It is intended as a header file for
% grlatex style files for typesetting greek texts. (e.g. grarticle, 
% grbook etc.)
% Note that this file can used under normal latex with the use of
% the macro definitions greek.sty. The only problem is the lack of hyphenation
% patterns for greek in that case.

%
%	First of all we make sure that the greek macros for KD fonts
%	are loaded.
%
\ifx\gr@@kformatloaded\relax
 \else
   \input greek.sty
\fi
%
% We need to enter a global greek mode, i.e. define the new catcodes and 
% default language
%
\let\~=~ 			% Save the meaning of ~
\gr@@km@de			% Load the catcode definitions for greek mode
\language\greek			% Switch to greek Hyphenation patterns
%
%	Remember: We need to inverse the greek-latin modes.
%		This means redefinition of certain things:
%
%	I. create a latin environment
%	Inside the environemnt everything is like in the standard LaTeX Mode
%
\newenvironment{latin}{\language0\l@tinm@de%
\t@f@m\t@f@nt\ignorespaces}%
{\xdef\t@f@nt{\the\font}\xdef\t@f@m{\noexpand\fam\the\fam}}
\gdef\t@f@nt{\rm}
\gdef\t@f@m{\fam0}
%
% 	Redifine the set greek macro to point to latin instead of greek
%
\gdef\@setgr@@k{\gdef\t@f@nt{\rm}\ifnum\language=\greek\gr\else\rm\fi}
%
%	Finally we need to redifine the today macro
%
\def\today{\number\day\space \ifcase\month\or
 Ianouar'iou\or Febrouar'iou\or Mart'iou\or April'iou\or Ma'iou\or Ioun'iou\or
 Ioul'iou\or Augo'ustou\or Septembr'iou\or Oktwbr'iou\or Noembr'iou\or 
 Dekembr'iou\fi\space \number\year}
