+     *
+     * This interface is a condensed of variant of the more general
+     * @see URLHandler interface, designed to make bodypart-dependent
+     * link operations possible without exposing KMail-internal
+     * classes.
+     *
+     * Implementation-wise, these handlers are called as a nested
+     * Chain Of Responsibilty by an internal implementation of
+     * URLHandler.
+     *
+     * You can create a link whose handling is passed to this handler
+     * by using BodyPart::makeLink( const QString & path ). \a path is
+     * what * is passed back to the methods of this interface.
+     *
+     * Note that the BodyPart interface does not provide a means of
+     * learning the content type of the body part passed. This is
+     * intentional. It is expected that either separate
+     * BodyPartURLHandlers are created for these purposes or else the
+     * information encoded into the path parameter by the
+     * BodyPartFormatter.
