18            <p>
19            In order to measure the code coverage of a page on <code>http://example.com/</code>,
20            you must run <code>jscoverage</code> to create a <code>jscoverage.html</code> file on the
21            <code>example.com</code> server.  You cannot use <code>http://example.org/jscoverage.html</code>
22            to measure the code coverage of a page located on <code>http://example.com/</code>.

26            The fundamental reason for this limitation is the

28            for untrusted JavaScript.

32            (In fact, the current version of JSCoverage is slightly more restrictive
33            than this: it requires that the JavaScript being measured reside under the
34            same <strong>directory</strong> as the <code>jscoverage.html</code> file.)
