usage="$(basename "$0") [-h] (java|cpp) name [-d test_dir] [-m] [-A] [arg] [arg]...
A script designed to run the integration tests.
This script should only be run on the roborio.
Where:
    -h    Show this help text
    name  The name of the user trying to run the tests (used for driver station)
    -d    The directory where the tests have been placed.
          This is done to prevent overwriting an already running program
          in the case where another user already has the driver station mutex.
          This scrip will automatically move the test into the ${DEFAULT_TEST_DIR}
          directory when the driver station mutex is released.
          Default: Assumes the test is in the same directory as this scrip.
    -m    The driver station mutex will be handled manually.
    -A    Do not use the default arguments for the given language.
    arg   The arguments to be passed to test."
