% Motivation
% ==========
% 
% By default, the ``\alpha`` -- ``\Omega`` macros for Greek letters
% 
% * are only valid in mathematical mode
% 
% * do not change shape (default shape is italic)
% 
% In Greek text fonts with the LGR font encoding, letters are
% accessible by a Latin transcription. 
% 
% This package provides a set of macros that can be used to access Greek
% symbols from a font in LGR encoding (e.g. the `CB fonts`_) without the
% need for an explicite font-encoding switch.
% 
% The macro names follow the established scheme to prepend ``\text*`` to
% the Adobe glyph name (if it exists) or the corresponding math-macro, so
% ``\textalpha`` -- ``\textOmega`` prints α – Ω.
% 
% * In combination with the ``\text`` macro from amsmath, this can be
%   used to get matching upright and bold upright Greek symbols in math
%   as well.
% 
% * In combination with ``\usepackage[utf8]{inputenc}`` and the
%   accompanying ``lgrenc.dfu`` file, Unicode input of Greek characters
%   is supported.
% 
% This is done using NFSS default definitions as explained in the
% fntguide_ (section 5.3).
% 
% Attention
%   While the macros work reasonably well for single letters, the
%   automatic font-encoding switches behind the doors destroy the
%   kerning between the letters.
% 
%   Text composites (replacement of accent+character with a pre-composed
%   character) work in LGR, but not in other encodings (due to the
%   forth-and-back font encoding switch).  
% 
%   Therefore, Greek text should be written with the help of babel_,
%   setting the language to either ``greek`` or ``polutonikogreek``.
% 
%   
% Implementation
% ==============
% 
% This package requires the extended font encoding definitions::

\input{lgrxenc.def}


% Greek Alphabet
% --------------
% 
% Define the ``text*`` marcos as default for all font encodings::

\DeclareTextSymbolDefault{\textEta}{LGR}
\DeclareTextSymbolDefault{\textTheta}{LGR}
\DeclareTextSymbolDefault{\textIota}{LGR}
\DeclareTextSymbolDefault{\textKappa}{LGR}
\DeclareTextSymbolDefault{\textLambda}{LGR}
\DeclareTextSymbolDefault{\textMu}{LGR}

% Diacritics
% ----------
% 
% Diacritics are defined via "named" macros in ``lgrxenc.def``. Make them
% default in any encoding::

\DeclareTextAccentDefault{\Dasia}{LGR}
\DeclareTextAccentDefault{\Psili}{LGR}
\DeclareTextAccentDefault{\Tonos}{LGR}
\DeclareTextAccentDefault{\Varia}{LGR}
\DeclareTextAccentDefault{\Perispomeni}{LGR}
\DeclareTextAccentDefault{\Dialytika}{LGR}
%
\DeclareTextAccentDefault{\DasiaOxia}{LGR}
\DeclareTextAccentDefault{\DasiaVaria}{LGR}
\DeclareTextAccentDefault{\DasiaPerispomeni}{LGR}
\DeclareTextAccentDefault{\PsiliOxia}{LGR}
\DeclareTextAccentDefault{\PsiliVaria}{LGR}
\DeclareTextAccentDefault{\PsiliPerispomeni}{LGR}
\DeclareTextAccentDefault{\DialytikaTonos}{LGR}
\DeclareTextAccentDefault{\DialytikaVaria}{LGR}
\DeclareTextAccentDefault{\DialytikaPerispomeni}{LGR}
