          Usage: syntax_suggest <file> [options]

          Parses a ruby source file and searches for syntax error(s) such as
          unexpected `end', expecting end-of-input.

          Example:

            $ syntax_suggest dog.rb

            # ...

              > 10  defdog
              > 15  end

          ENV options:

            SYNTAX_SUGGEST_RECORD_DIR=<dir>

            Records the steps used to search for a syntax error
            to the given directory

          Options:
        EOM

        opts.version = SyntaxSuggest::VERSION

        opts.on("--help", "Help - displays this message") do |v|
          @io.puts opts
          options[:exit] = true
          @exit_obj.exit
        end

        opts.on("--record <dir>", "Records the steps used to search for a syntax error to the given directory") do |v|
          options[:record_dir] = v
        end

        opts.on("--terminal", "Enable terminal highlighting") do |v|
          options[:terminal] = true
        end

        opts.on("--no-terminal", "Disable terminal highlighting") do |v|
          options[:terminal] = false
        end
      end
    end
