+"""Runs various libyuv tests through valgrind_test.py.
+
+This script inherits the chrome_tests.py in Chrome, but allows running any test
+instead of only the hard-coded ones. It uses the -t cmdline flag to do this, and
+only supports specifying a single test for each run.
+
+Suppression files:
+The Chrome valgrind directory we use as a DEPS dependency contains the following
+suppression files:
+  valgrind/memcheck/suppressions.txt
+  valgrind/memcheck/suppressions_mac.txt
+  valgrind/tsan/suppressions.txt
+  valgrind/tsan/suppressions_mac.txt
+  valgrind/tsan/suppressions_win32.txt
+Since they're referenced from the chrome_tests.py script, we have similar files
+below the directory of this script. When executing, this script will setup both
+Chrome's suppression files and our own, so we can easily maintain libyuv
+specific suppressions in our own files.
