        Then the output should contain "Usage: typogruby [options] filename [filename, ...]"

        Given a file named "input.html" with:
        """
        <p>"This IS a simple file!</p>
        """
        When I run `typogruby input.html`
        Then the output should contain exactly:
        """
        <p><span class="dquo">&#8220;</span>This <span class="caps">IS</span> a simple&nbsp;file!</p>
