+ * @author Martin Trapp, Christian Schaefer
+ *
+ * The dump format of most functions is vcg. This is a text based graph
+ * representation. Some use the original format,
+ * but most generate an extended format that is only read by some special
+ * versions of xvcg or by the comercialized version now calles aiSee.
+ * A test version of aiSee is available at
+ * http://www.absint.de/aisee/download/index.htm.
+ *
+ * Most routines use the name of the passed entity as the name of the
+ * file dumped to.
