+The most useful switch to anaylze parts of a highly coupled system is
+--dont-follow=random.dll (accepting a list as above). This will show
+random.dll in the resulting graph in gray. But it will not drag in 
+any dependencies below.
+
+If you have a small graph it may be useful to not only show the 
+number of symbols used but their name. Giving --symbols=n all edges 
+with n or less symbols will have the (mostly demangled) name of the 
+symbols printed as text.
+
+Finally there is the switch --dump for people prefering the textual
+representation over some graph.
