From fa78d0fbe45a7f16d5d30c3d4e3ad30dc4933e8f Mon Sep 17 00:00:00 2001
From: Ka-Ping Yee <ping@zesty.ca>
Date: Tue, 4 Dec 2001 18:45:17 +0000
Subject: Add "file" argument to Hook constructor. By default, save sys.stdout
 in self.file when a Hook instance is created     (e.g. when cgitb.enable() is
 called).
