-# A Composition of a User record and it's identity records.
+# The Account model takes care of the livecycle of a user.
+# It composes a User record and it's identity records.
+# It also allows for other engines to hook into the livecycle by
+# monkeypatching the create, update and destroy methods.
+# There's an ActiveSupport load_hook at the end of this file to
