-Design discussion.
-
-The primary task of this module is to add a host route to the PPTP
-server so that the kernel continues to deliver PPTP control and data
-connection packets to the server despite the new PPP interface that is
-created.  The flag --no-host-route is to disable this (not yet implemented).
-
-A secondary task may be to implement all-to-tunnel routing if the
-appropriate flag is specified on the command line.  The flag
---route-all is to implement this (not yet implemented).
-
-Caveat.
-
-It is not possible from the "ip route" command to determine if a host
-route already exists, so it isn't practical to put the routing table
-back exactly as it was.
-
-We have a choice of either leaving our route lying around, or
-destroying a route that the user had pre-arranged.  Both are
-unfortunate.  The flag --remove-host-route is to remove the route
-regardless (not yet implemented).
