From 7238988657b3676e115e2528e83722a7d17e36c8 Mon Sep 17 00:00:00 2001 From: Fred Drake Date: Mon, 13 Apr 1998 01:31:10 +0000 Subject: Fixed example to load the startup file from a script (didn't test for the file's existance). Removed some XXX comments about extension modules which support pickling. Added text from AMK about the readline and rlcompleter modules.
