# or Dev (on Linux) installed directory. Testing ANGLE this way is much faster than compiling
# Chromium from source. The script checks for the most recent build in a set of search paths,
# and copies that into:

# - /opt/google/chrome-unstable on Linux
# - the most recent Canary installation folder on Windows.
# - /Applications/Google\ Chrome\ Canary.app on macOS
