      Command to run to create and communicate with local network
      interface.  Passed to sh -c.  Must speak SLIP on stdin/stdout.
      The following interpolations aare substituted:

+     (For compatibility with older hippotat, %(var)s is supported too
+     but this is deprecated since the extra `s` is confusing.)

      On server: applies to all clients; not looked up in
       client-specific sections.
