+====================================
+Testing head checking code: Case A-2
+====================================
+
+Mercurial checks for the introduction of multiple heads on push. Evolution
+comes into play to detect if existing heads on the server are being replaced by
+some of the new heads we push.
+
+This test file is part of a series of tests checking this behavior.
+
+Category A: checking simple case invoving a branch being superceeded by another.
+TestCase 2: multi-changeset branch
+
+.. old-state:
+..
+.. * 2 changeset branch
+..
+.. new-state:
+..
+.. * 2 changeset branch succeeding the old one
+..
+.. expected-result:

+.. * push allowed
