  -h, --help         Will print out this message and list out
                     CLI options available.

  -i, --ignore       JS structured regex to ignore.
                     Multiple can be set by separating with a space.
                     Use single quotes to prevent shell expansion.

  -l, --local-dev    Allows for local development of conssert
                     by properly configuring directory

                     paths - default: false
  -p, --port         Port conssert will run on and server
                     files from - default: 3000

  -q, --quiet        Report errors only rather than standard output
                     of tests and assets being served. - default: false

  -v, --version      Output the version number of conssert being used.

  -w, --watch        Will automatically re-run tests when file
                     modifications are detected. If --ignore option is
                     used, the files matching given pattern(s) will not
                     be watched.
