     AFCComp man page description

I haven't merged the port 80/81 changes as they've been
questioned :-/

o Avoid some alpha/Wall warnings.
o Becareful about aligning mbufs before casting bits of them.
o Don't accept pap/chap packets unless we're in the right PHASE.
o Be smarter when detecting HDLC headers.
o Use a combination of the peers accmap and our own when async
  encoding, and back out the previous LCP changes.
o Add an extra sig_Handle() to avoid hanging under certain
  curcumstances.
o Tidy up macro usage in the man page.
o Don't change \r\n to \r\r\n in tty raw mode.

o Add radius support.
o Add ``alias proxy'' and ``alias pptp'' support.
o Support server-side M$Chap authentication.
o Support client & server-side M$LANMan authentication.
o Support ``!program'' passwords.
o Use pipes only for unidirectional IPC.
o Extend ``set *retries'' commands.
o Don't ResetReq when doing Predictor compression.
o Delay carrier detection by a default of 1 second and implement
  ``set cd''.
o Implement incremental redial timeouts via ``set redial''.
o Don't use hard-coded quotes or brackets in the man page.
o ``random'' redials means 1-30 seconds, not 0-29.
o Close rather than hanging if the peer never responds to auth requests.
o Nuke outstanding authentication request timers when the layer is closed
  unexpectedly.
o Log CCP errors as in the CCP log (not as a WARNING).
o Ensure that all TLU/TLD and TLS/TLF pairs are balanced.
o OR the peers ACCMAP with our own during LCP negotiations.
o Set the interface netmask correctly and show it in ``show ipcp''.
o Drop the correct diagnostic connections and remove the correct local
  domain socket from ``set server''.
o If our config file doesn't exist, moan about that rather than claiming
  that the ``default'' section doesn't exist.

     a bum name to return as 0.0.0.0... we don't want ``delete xxx''
     to delete the default route when xxx doesn't resolve.

     Support IP number specifications as the host when specifying
     a tcp-style device (rather than *just* hostnames).

``iface clean'' is used in auto mode while there
are no active links.
