# This is a small script for manually launching valgrind, along with passing
# it the suppression file, and some helpful arguments (automatically attaching
# the debugger on failures, etc). Run it from your repo root, something like:
# $ sh ./tools/valgrind/valgrind.sh ./out/Debug/chrome
#
# This is mostly intended for running the chrome browser interactively.
# To run unit tests, you probably want to run chrome_tests.sh instead.
# That's the script used by the valgrind buildbot.
