 %   ====== ========== =========================================================
-% 
+%
 % Motivation
 % ==========
-% 
+%
 % By default, the ``\alpha, \beta, ...`` macros for Greek letters
 % are only valid in mathematical mode.
-% 
+%
 % 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.
-% 
+%
 % If used together with the ``utf8`` option of inputenc_, literal Unicode
 % characters can be used for Greek symbols in mathematical formulas.
-% 
+%
 % .. Attention::
 %    The macros work well in any font encoding for single symbols.
 %    However, with 8-bit TeX, 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 proper hyphenation.
