+#!/bin/bash
+# This script fetches the libaom 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 libaom release.
+# Legacy manual instructions:
+# 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
