# This script is a copy of the chrome_tests.sh wrapper script with the following
# changes:
# - The locate_valgrind.sh of Chromium's Valgrind scripts dir is used to locate
#   the Valgrind framework install.
# - webrtc_tests.py is invoked instead of chrome_tests.py.
# - Chromium's Valgrind scripts directory is added to the PYTHONPATH to make it 
#   possible to execute the Python scripts properly.
