# To update test data tarball, follow these steps:
# 1. Clone the upstream repo and check out the relevant tag,
# or download the release tarball
# 2. Regular cmake configure (options don't matter here):
# cd build && cmake ..
# 3. Set LIBAOM_TEST_DATA_PATH to the directory you want and
# run the "make testdata" target:
# LIBAOM_TEST_DATA_PATH=../libaom-3.7.1-testdata make testdata
# This will download the test data from the internet.
# 4. Create a tarball out of that directory.
# cd .. && tar cvaf libaom-3.7.1-testdata.tar.xz libaom-3.7.1-testdata
