  [2013/07/24 0.1.3 Composite definitions for XeTeX and LuaTeX]
  
Domposite definitions for ``alphabeta.sty`` with XeTeX and LuaTeX.

Changelog:
  .. class:: borderless

  ==========  ===== =========================================================
  2013-09-12  0.1   initial version
  2013-10-01  0.1.1 remove clashing defs for legacy characters with oxia.
  ==========  ===== =========================================================

The alphabeta_ package re-defines the math macros for Greek letters to work
in both, text and math mode, so that Greek letters can be specified with
the established command names in text, too. 

The NFSS TextComposite mechanism looks for the next token without expanding
it. In order to let compositions like ``\>"\alpha`` work as expected we
define TextComposites with the `letter name commands`.

For use with Unicode fonts (XeTeX/LuaTeX), we need to define composite
commands for the EU1 and EU2 encoding

Greek and Coptic
