+Usage:
+
+\renewcommand{\the<counter>}{\greek{<counter>}}
+\renewcommand{\the<counter>}{\Greek{<counter>}}
+
+e.g. \renewcommand{\theenumi}{\greek{enumi}}
+
+Provides \greek and \Greek for counters just like \alph. No switch to 
+math mode is needed. \varepsilon, \vartheta and \varphi are preferred, 
+but \pi and \sigma.
+
+Version 3 doesn't need the package amstxt any longer, since it relies on 
+\ensuremath. Also fixed a bug in the handling of Omega.
