     - update to a successor if the working directory parent is
       obsolete
 
-    By default, takes the first troubled changeset that looks relevant.

-    (The logic is still a bit fuzzy)
+    By default a single changeset is evolved for each invocation and only
+    troubles changesets that would evolve as a descendant of the current
+    working directory will be considered. See --all and --any options to change
