+====================================
+Testing head checking code: Case B-1
+====================================
+
+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 B: checking simple case involving pruned changesets
+TestCase 1: single pruned changeset
+
+.. old-state:
+..
+.. * 1 changeset branch
+..
+.. new-state:
+..
+.. * old branch is pruned
+.. * 1 new unrelated branch
