# 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.
# The sysroot is needed to ensure that binaries that get built will run on

# The sysroot image could be constructed from scratch based on the current state

# don't want upstream changes to Debian to effect the chromium build until we
# choose to pull them in). The images will normally need to be rebuilt every
# time chrome's build dependencies are changed but should also be updated
# periodically to include upstream security fixes from Debian.

This includes at least the sysroot for host architecture, and the 32-bit

compile sysroot for ARM/MIPS if cross compiling environment can be detected.
Another reason we're installing this by default is so that developers can
compile and run on our supported platforms without having to worry about
flipping things back and forth and whether the sysroots have been downloaded
