  -c file | --config file        use a config file for controlling tests
  -D dir  | --dir dir            use dir rather than WT_TEST.
                                 dir is removed/recreated as a first step.
  -d      | --debug              run with 'pdb', the python debugger
  -g      | --gdb                all subprocesses (like calls to wt) use gdb
  -h      | --help               show this message
  -j N    | --parallel N         run all tests in parallel using N processes
  -l      | --long               run the entire test suite
  -p      | --preserve           preserve output files in WT_TEST/<testname>
  -t      | --timestamp          name WT_TEST according to timestamp
  -v N    | --verbose N          set verboseness to N (0<=N<=3, default=1)

Tests:
  may be a file name in test/suite: (e.g. test_base01.py)
  may be a subsuite name (e.g. 'base' runs test_base*.py)

  When -C or -c are present, there may not be any tests named.
