From 42251323b4d0a25b2b0a5697d6ee2cdc60427a12 Mon Sep 17 00:00:00 2001
From: Jack Jansen <jack.jansen@cwi.nl>
Date: Wed, 8 May 2002 22:13:51 +0000
Subject: [PATCH] Fixed string and dict conversion, and implemented booleans
 and numbers (int and float). I think we now have enough CFType support to
 start on plists and CFpreferences!

Transparent handling of unknown CFType objects still TBD.
