+--------
+
+ * open-pool
+
+ Open the pool of scenes.
+
+ * train-detector
+
+ Create a new detector from the training scenes.
+
+ * compute-thresholds
+
+ Compute the thresholds of the detector classifiers from the
+ validation set to obtain the required wanted-true-positive-rate.
+
+ * test-detector
+
+ Run the detector on the test scenes.
+
+ * sequence-test-detector
+
+ Visit nb-wanted-true-positive-rates rates between 0 and
+ wanted-true-positive-rate, for each compute the detector
+ thresholds on the validation set and estimate the error rate on
+ the test set.
+
+ * write-detector
+
+ Write the current detector to the file detector-name
+
+ * read-detector
+
+ Read a detector from the file detector-name
+
+ * write-pool-images
+
+ For every of the first nb-images of the pool, save one PNG image
+ with the ground truth, one with the corresponding referential at
+ the reference scale, and one with the feature material-feature-nb
+ from the detector. This last image is not saved if either no
+ detector has been read/trained or if no feature number has been
+ specified.
