+#!/bin/bash
+# This script fetches the libvpx sources, checks out the appropriate tag
+# and generates a tarball that can be placed in a devspace or other
+# web-accessible site and added to SRC_URI for a given libvpx release.
+# Legacy manual instructions:
+# To create a new testdata tarball:
+# 1. Unpack source tarball or checkout git tag
+# 2. mkdir libvpx-testdata
+# 3. export LIBVPX_TEST_DATA_PATH=libvpx-testdata
+# 4. ./configure --enable-unit-tests --enable-vp9-highbitdepth
+# 5. make testdata
+# 6. tar -caf libvpx-testdata-${MY_PV}.tar.xz libvpx-testdata
