  Add script for updating Canary ANGLE DLLs.
  
  This script makes debugging in Chrome easier on Windows. It scans
  for the latest set of ANGLE DLLs among many search paths, and then
  copies them to the latest Chrome Canary binary directory. It also
  backs up the original DLLs if it finds them.
  
  BUG=None

  #   Helper script that copies Windows ANGLE DLLs into the Canary
  #   application directory. Much faster than compiling Chrome from
  #   source. The script checks for the most recent DLLs in a set of
  #   search paths, and copies that into the most recent Canary
  #   binary folder. Only works on Windows.
