Trampoline: An operation which will forward control to a delegate.
Maps f(device_id) -> g(platform, config, device_id)
Trampolines reduce the complexity for invoking cobalt/starboard binaries and tests by reading parameters from the metadata.json file of a Cobalt Archive. The delegate is then run with the full command-line argument set including platform and configuration data. The calling signature is therefore stable and any Cobalt archive can be run the same binaries/tests using the same shell command.
Please see go/cobalt-archive-doc
Example: python __cobalt_archive/run/run_cobalt.py --device_id IP
Could translate into: python starboard/tools/example/app_launcher_client.py -t cobalt --platform linux --config devel --device_id IP
