+Scoring interface
+=================
+
+Files in this directory should be _modules_ implementing the following
+interface:
+
+ - `stats_needed(Match) => Array[]=Symbol`
+
+   Returns which statistics need to be collected for this scoring
+   algorithm.
+
+ - `score(Match) => Hash[User]=Integer`
+
+   User scores for this match, assuming statistics have been
+   collected.
