From 397beebc19dfac0417a64fdbcfb4e6657f6ad9f5 Mon Sep 17 00:00:00 2001
From: "terry%mozilla.org" <>

Subject: Add support for a new "keywords" feature.  This lets some central
 authority maintain a list of keywords, and users can associate any keyword
 with any bug.

The new functionality won't appear until at least one keyword is
defined.

Note that you *must* run the "checksetup.pl" script after updating
this change, in order to create the new required tables "keywords" and
"keyworddefs".
