+% 
 % Motivation
 % ==========
-%
+% 
 % By default, TeX macros for Greek letters are only valid in mathematical
 % mode. This package sets up a suitable `font encoding`_ and `LaTeX internal
 % character representations` (LICR) definitions for Greek (``\textalpha`` --
 % ``\textOmega``).
-%
+% 
 % To allow documents using Greek LICR macros without worrying about the TeX
 % engine used to compile them, this package tests the declared font encodings
 % and does "the right thing" to set up Greek text font support:
-%
+% 
 % * If the Unicode font encodings EU1 (XeTeX) or EU2 (LuaTeX) are declared,
 %   before loading this package (e.g. via ``fontspec``) the package provides
 %   Greek LICR definitions for them.
-%
+% 
 % * Otherwise, the `LGR font encoding`_ is set as `default font encoding`
 %   (cf. fntguide_ section 5.3) for Greek.
-%
+% 
 % Advantages:
-%
+% 
 % * Symbols from a Greek text font (e.g. the `CB fonts`_) can be accessed
 %   without the need for an explicite font-encoding switch anywhere in the
 %   text.
-%
+% 
 % * Unicode input of Greek characters is supported
-%
+% 
 %   + via ``\usepackage[utf8]{inputenc}`` and ``lgrenc.dfu`` from
 %     greek-inputenc_ for 8-bit TeX or XeTeX/LuaTeX in 8-bit compatibility
 %     mode in any font encoding (see textalpha-doc.tex_).
-%
+% 
 %   + natively by XeTeX/LuaTeX for Unicode fonts. As inputenc_ does not work
 %     with these engines, text input can be done via the Latin transcription
 %     or LICR but *not via literal Unicode characters* for 8-bit font encodings
 %     like LGR (see greek-euenc-doc.tex_).
-%
+% 
 % .. Attention:: The macros work well in any font encoding for single symbols.
 %    However, with 8-bit TeX engines, the automatic font-encoding switches
 %    behind the doors interfere with kerning between letters and replacement
 %    of accent+character with a pre-composed character.
-%
+% 
 %    Therefore, Greek text should be written with the help of babel_ or
 %    polyglossia_ (setting the language to ``greek``) or wrapped in the
 %    provided ``ensuregreek`` macro.  Using babel_ or polyglossia_ also helps
 %    to ensure correct hyphenation of Greek text.

-%

+% 
 %      \usepackage[normalize-symbols,keep-semicolon]{textalpha}

 % To give ``textalpha.sty`` a chance of finding out which `font encodings`_
 % are used, load it after fontspec_ and/or fontenc_.
