+% This document is largely a stub used to allow the email package docs
+% to be formatted separately from the rest of the Python
+% documentation.  This allows the documentation to be released
+% independently of the rest of Python since the email package is being
+% maintained for multiple Python versions, and on an accelerated
+% schedule.
