From 42181dba8ecf9736ae0ec2384aa4307533c835e1 Mon Sep 17 00:00:00 2001
From: Fred Drake <fdrake@acm.org>
Date: Tue, 9 Jan 2001 22:02:10 +0000
Subject: Added a --global-module-index option to specify a (possibly relative)
 URL to the Global Module Index for a set of documents.  This is used to
 include a reference to the global index from the per-document module indexes,
 so that it is just a little easier to find.

(Someone suggested this, but I do not remember who.  Please let me know if
it was you -- thanks!)
