 Note that GEval is only about machine learning evaluation. No actual

+## Examples
+
+Let us download a Gonito.net challenge:
+
+    git clone git://gonito.net/sentiment-by-emoticons
+
+The task is to predict the sentiment of a Polish short text -- whether
+it is positive or negative (or to be precise: to guess whether a
+positive or negative emoticon was used).
