+Bugzilla Assumptions
+--------------------
+
+This script makes some assumptions regarding your Bugzilla installation.
+#. Grouping bugs all have a common description prefix.  The default prefix is "META: ".  Bugs that are part of a group are made into subtasks of that group.
+#. Not all bugs will have an time estimate.  Those bugs are flagged and assigned a default effort.
+#. The set of priority values is ["P1", "P2", "P3", "P4", "P5"].
+#. The lowest bug priority of "P5" means that the bug is not prioritized.  Those bugs are flagged.
