Run an interpreter with different modes (mode_list) on all *.js files in

the interpreter.
Test reports are generated in TXT and HTML format. Paths to generated reports
are printed upon a finished run.
Options:
-i, --interpreter Use the specified interpreter (default: '%s').
-t, --timeout Timeout in seconds for the interpreter to process a single
file (default: '%s').
-d, --input-dir *.js files will be searched in input_dir. (default: '%s').
-m, --modes Run the interpreter with specified modes. mode_list is a
comma separated list (valid: '%s',
default: '%s').
-p, --printers Print results by specified printers. printers is a comma
separated list (valid: '%s', default: '%s').
-j, --jobs Allow N jobs at once (default: %s).
