+            Perf calculates a variety of performance metrics suitable for boolean classification problems. Metrics include: accuracy, root-mean-squared-error, cross-entropy, 
+            precision, recall, precision/recall break-even point and F-score, area under the ROC curve, lift, weighted cost, top 1, top 10, rank of lowest positive case, 
+            q-score, several measures of probability calibration, etc.
+
+            PERF requires a C compiler.
