  **** Output ****

    -f, --format FORMATTER           Choose a formatter.
                                       [p]rogress (default - dots)
                                       [d]ocumentation (group and example names)

    -o, --out FILE                   Write output to a file instead of $stdout. 
                                     This option applies to the previously 
                                     specified --format, or the default format

    -p, --[no-]profile [COUNT]       Enable profiling of examples

    -w, --warnings                   Enable ruby warnings

  **** Filtering/tags ****

  In addition to the following options for selecting specific files,
  groups, or examples, you can select a single example by appending
  the line number to the filename:

      rspec path/to/a_spec.rb:37

    -P, --pattern PATTERN            Load files matching pattern 
                                     (default: "spec/**/*_spec.rb").
        --exclude-pattern PATTERN    Load files except those matching pattern. 
                                     Opposite effect of --pattern.
    -e, --example STRING             Run examples whose full nested names 
                                     include STRING (may be
                                     used more than once)
    -t, --tag TAG[:VALUE]            Run examples with the specified tag, 
                                     or exclude examples
                                     by adding ~ before the tag.
                                       - e.g. ~slow
                                       - TAG is always converted to a symbol
        --default-path PATH          Set the default path where RSpec looks for examples (can
                                       be a path to a file or a directory).

  **** Utility ****

    -v, --version                    Display the version.
    -h, --help                       You're looking at it.
