The Roaring Penguin manual states these goals, and I think we could do
well to adapt them for n4:

       o      It must work.

       o      It must be a user-space program and  not  a  kernel
              patch.

       o      The code must be easy to read and maintain.

       o      It  must be fully compliant with RFC 2516, the pro­
              posed PPPoE standard.

       o      It must never hang up forever -- if the  connection
              is broken, it must detect this and exit, allowing a
              wrapper script to restart the connection.

       o      It must be fairly efficient.

       I believe I have achieved all  of  these  goals,  but  (of
       course) am open to suggestions, patches and ideas.  See my
       home  page,  http://www.roaringpenguin.com,  for   contact
