+We can get this using the following command:
+
+ git-rebase --onto master next topic
+
+
+Another example of --onto option is to rebase part of a
+branch. If we have the following situation:
+
+------------
+ H---I---J topicB
+ /
+ E---F---G topicA
+ /
+ A---B---C---D master
+------------
+
+then the command
+
+ git-rebase --onto master topicA topicB
+
+would result in:
+
+------------
+ H'--I'--J' topicB
+ /
+ | E---F---G topicA
+ |/
+ A---B---C---D master
+------------
+
+This is useful when topicB does not depend on topicA.
