+        Specify an alternate path where the HTML documentation resides. This

+        will be used if the documentation in question cannot be found under

+        the value for <tt>help.htmlpath</tt>. File system paths and URLs are

+        supported, but note that if <tt>help.htmlpath</tt> is set to a URL then this

+        path when help is displayed in the <em>web</em> format.
