From 1176f4538d46a9c77da3095a5c2109e74cfc542a Mon Sep 17 00:00:00 2001
From: "Shawn O. Pearce" <sop@google.com>
Date: Fri, 28 Nov 2008 15:05:48 -0800
Subject: [PATCH] Build a standard .war file for Gerrit

We also include .gz versions of every static resource, because
this allows Jetty (and possibly other servers) to efficiently
send the pre-compressed static resource to the client.
