#   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.
