"""Runs a script that can run as an isolate (or not).
The main requirement is that
is passed on the command line to run_isolated_script_tests. This gets
remapped to the command line argument --write-full-results-to.
json is written to that file in the format produced by
Optional argument:
is a double-colon-separated ("::") list of test names, to run just that subset
of tests. This list is parsed by this harness and sent down via the --test-list
This script is intended to be the base command invoked by the isolate,
followed by a subsequent Python script. It could be generalized to
invoke an arbitrary executable.
