Subject: [PATCH] Document that Python 2.3 requires cdecimal module for full
functionality.
This has been true for some time, but we were leaving users to discover it
the hard way.
Back-patch to 9.2. It might've been true before that, but we were claiming
Python 2.2 compatibility before that, so I won't guess at the exact
requirements back then.
