+HG METAEDIT
+===============================
+
+Setup the Base Repo
+-------------------
+
+We start with a plain base repo::
+
+  $ hg init $TESTTMP/metaedit; cd $TESTTMP/metaedit
+  $ mkcommit "ROOT"
+  $ hg phase --public "desc(ROOT)"
+  $ mkcommit "A"
+  $ mkcommit "B"
+  $ hg up "desc(A)"
+  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
+  $ mkcommit "C"
+  created new head
+  $ mkcommit "D"
+  $ echo "D'" > D
+  $ hg amend -m "D2"
+  $ hg up "desc(C)"
+  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
+  $ mkcommit "E"
+  created new head
+  $ mkcommit "F"
