[2013/05/03 v0.2 macros for Greek letters in text and math]

%  This package is part of the lgrx_ bundle.
%
% Changelog:
%   .. class:: borderless
%
%   ==========  ===== =========================================================
%   2012-06-26  0.1   initial version
%   2013-05-03  0.2   new accent macro names with lgrxenc.def 0.7
%   ==========  ===== =========================================================
%
% Motivation
% ==========
%
% By default, the ``\alpha, \beta, ...`` macros for Greek letters
% are only valid in mathematical mode.
%
% The `textalpha` 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 under the names
% ``\textalpha, \textbeta``, ..., ``\textOmega``.
%
% With this package, the math macros are redefined to work in both, text and
% math mode, so that Greek letters can be specified with the established
% command names in text, too.
%
% Attention
%   While the macros work reasonably well for single letters, the automatic
%   font-encoding switches behind the doors interferes with the kerning
%   between the letters and replacement of accent+character with a
%   pre-composed character.
%
%   Therefore, Greek text should be written with the help of babel_, setting
%   the language to either ``greek`` or ``polutonikogreek`` or wrapped in the
%   provided ``\ensuregreek`` macro.
%
%
% Implementation
% ==============
%
% This package extends the `textalpha` package::

\RequirePackage{textalpha}

% It uses the ``\TextOrMath`` test from the fixltx2e_ standard LaTeX
% package::

\RequirePackage{fixltx2e}

% .. _fixltx2e: http://www.ctan.org/pkg/fixltx2e
%
%
% Save math macros
% ----------------
%
% Provide an alias for the standard math commands::

\let\mathGamma\Gamma
\let\mathDelta\Delta
\let\mathTheta\Theta
\let\mathLambda\Lambda
\let\mathXi\Xi
\let\mathPi\Pi
\let\mathSigma\Sigma

\let\mathpsi\psi
\let\mathomega\omega

% Commands to access Greek letters by name
% ----------------------------------------
%
% For letters defined in math mode, the commands work in both, text and math.
%
% Some Greek letters look identic to Latin letters and can therefore not be
% used as variable symbols in math formulas. These letters are not defined in
% TeX's math mode, we define just an alias to the corrsponding ``\text...``
% command.

% TextCompositeCommands for the generic macros
% --------------------------------------------
%
% The NFSS TextComposite mechanism looks for the next token without expanding
% it. In order to let compositions like ``\TextGreek{\'\Alpha}`` or
% ``\TextGreek{\>"\alpha}`` work as expected we define TextComposites with the
% `letter name commands`. (Composition only works if the active font encoding
% is LGR). ::
