+# Project         : Mandrake Linux
+# Module          : share
+# File            : shadow.py
+# Version         : $Id$
+# Author          : Frederic Lepied
+# Created On      : Sat Jan 26 17:38:39 2002
+# Purpose         : loads a python module and creates another one
+# on stdout. All the functions of the module are shadowed according
+# to their doc string: "D" direct mapping, "1" indirect call but
+# name + first arg used as the key and all other cases indirect
+# call with the name as the key.
