# Update to latest chromium nightly on linux
# Script requires root to properly set up the sandbox
# https://code.google.com/p/chromium/wiki/LinuxSUIDSandboxDevelopment
# 
# I use it with a line like the following in my .bashrc:

#
#    Simple script to update OSX Chromium to the latest nightly build.
#    Will not download if you already have the latest (call with --force
#    to override this check)
