+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Automatic feedback-driven quota tuning.  Instead of setting the absolute quota
+value, users can provide feedback about how well DAMOS is achieving their goal.
+If the feedback says DAMOS is still not achieving the goal, DAMOS increases the
+quota.  If DAMOS is over-achieving the goal, DAMOS decreases the quota.
