# Set up some paths and re-direct the arguments to libyuv_tests.py

# 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. If it fails a fallback path is used instead
#   (../../chromium/src/third_party/valgrind/linux_x64) and a warning message
#   is showed by |show_locate_valgrind_failed_warning|.
# - libyuv_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.
