-# Script to install a Debian Wheezy sysroot for making official Google Chrome
-# Linux builds.
-# The sysroot is needed to make Chrome work for Debian Wheezy.
-# This script can be run manually but is more often run as part of gclient
-# hooks. When run from hooks this script should be a no-op on non-linux
-# platforms.
-
-# The sysroot image could be constructed from scratch based on the current
-# state or Debian Wheezy but for consistency we currently use a pre-built root
-# image. The image will normally need to be rebuilt every time chrome's build
-# dependancies are changed.
