+====================================
+Testing head checking code: Case E-1
+====================================
+
+Mercurial checks for the introduction of new heads on push. Evolution comes
+into play to detect if existing branches on the server are being replaced by
+some of the new one we push.
+
+This case is part of a series of tests checking this behavior.
+
+Category F: case involving changeset on multiple topic
+TestCase 1: moving a branch to another location
+
+.. old-state:
+..
+.. * 1-changeset on topic Y
+.. * 1-changeset on topic Z (above Y)
+..
+.. new-state:
+..
+.. * 1-changeset on topic Y
+.. * 1-changeset on topic Z (rebased away from A0)
+..
+.. expected-result:

+Test setup
+----------
+
+  $ mkdir E1
+  $ cd E1
+  $ setuprepos
+  creating basic server and client repo
+  updating to branch default
+  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
+  $ cd client
+  $ hg topic -r . Y
+  switching to topic Y
+  changed topic on 1 changesets to "Y"
+  $ hg topic Z
+  $ mkcommit B0
+  active topic 'Z' grew its first changeset
+  (see 'hg help topics' for more information)
+  $ hg push
+  pushing to $TESTTMP/E1/server
+  searching for changes
+  adding changesets
+  adding manifests
+  adding file changes
+  added 2 changesets with 1 changes to 2 files (+1 heads)
+  1 new obsolescence markers
