+          hg rebase -r 5f493448 -d stable

+      - splice a commit and all its descendants onto another part of history::
+
+          hg rebase --source c0c3 --dest 4cf9
+
+      - rebase everything on a branch marked by a bookmark onto the
+        default branch::
+
+          hg rebase --base myfeature --dest default
+
+      - collapse a sequence of changes into a single commit::
+
+          hg rebase --collapse -r 1520:1525 -d .
+
+      - move a named branch while preserving its name::
