# angle_deqp_bundle.py:
#   Makes a zip bundle allowing to run deqp tests, similarly to mb.py but
#    - trims most of the dependencies
#    - includes run_tests.sh (see below)
#    - lib.unstripped only included if --include-unstripped-libs
#    - does not depend on vpython
#    - just adds files to the zip instead of "isolate remap" with a temp dir
#
#  Example usage:
#    % scripts/angle_deqp_bundle.py out/Android angle_deqp_gles31_rotate90_tests angle_deqp_bundle.zip
#
#    (transfer the zip elsewhere)
#    % unzip angle_deqp_bundle.zip -d angle_deqp_bundle
#    % angle_deqp_bundle/run_tests.sh --list-tests
#    % angle_deqp_bundle/run_tests.sh --gtest_filter='dEQP-GLES31.functional.primitive_bounding_box.triangles.*'
