+
+Register one of the controller's subs to be called whenever an URL has
+to be generated (e.g. for sort and pagination links). This is a way
+for the controller to add additional parameters to the URL (e.g. for
+filter parameters).
+
+The C<$sub> parameter can be either a code reference or the name of
+one of the controller's functions.
+
+The value returned by this C<$sub> must be either a single hash
+reference or a hash of key/value pairs to add to the URL.
