     <p>
+      Robots exlusion support in the link checker is based on the
+      <a href="http://search.cpan.org/dist/libwww-perl/lib/LWP/RobotUA.pm">LWP::RobotUA</a>
+      Perl module.  It currently supports the
+      "<a href="http://www.robotstxt.org/wc/norobots.html">original 1994 version</a>"
+      of the standard.  The robots META tag, ie.
+      <code>&lt;meta name="robots" content="..."&gt;</code>, is not supported.
+      Other than that, the link checker's implementation goes all the way
+      in trying to honor robots exclusion rules; if a
+      <code>/robots.txt</code> disallows it, not even the first document
+      submitted as the root for a link checker run is fetched.
+    </p>
+
+    <p>
       Note that <code>/robots.txt</code> rules affect only user agents
       that honor it; it is not a generic method for access control.
