# -d (DEBUG_MODE) drops the user into the remote shell after the tests complete - this
#      is not allowed if the output is in JSON (done by passing .json to the test runner)
# -i (SHOW_INFO) displays info about the remote server including PHP/PHPUnit
#      version and info about missing PHP extensions or database command line tools - this
#      mode will not run any tests
# -a (ADD_KEY) this adds the current user's SSH public key to all of the remote accounts
#      listed - no tests will be run or info shown with this flag
# -n 0-9 (CONCURRENT) this number of tests will be run conccurently instead of sequentially
# -p (PARALLEL_DB) if this flag is present, all tests for each type of database will be
#      run sequentially on all specified hosts, but all database types will be run at the
#      same time and all non-database tests will be run in parallel with all of the database tests
