From 1fca149ca717c64ae05edb534a61a909dc0a6d11 Mon Sep 17 00:00:00 2001 From: "mpcomplete@google.com" Date: Fri, 15 May 2009 22:23:43 +0000 Subject: Introducing the Utility process, which handles the unpacking and verification of extension packages. This is a first pass. In the second pass, I will add support for transcoding the manifest and any images in the browser process.
