Provisional README

greproxy is a daemon to turn an unreliable GRE tunnel (e.g. over
the open Internet) into a more reliable one; instead of

  A -> Internet -> B,

do

  A -> greproxy -> Internet -> greproxy -> B

It is primarily useful for UDP video streams (e.g. multicast); it is not very
well tuned for anything else.

Primary features:

 - Talks standard GRE, e.g. with Cisco or Juniper equipment.
 - Can reorder packets (within reason), based on GRE sequence numbers.
 - Forward error correction (through fecpp) using Reed-Solomon;
   can handle a certain amount of packet loss without any more ill
   effects than increased jitter. (Only works when talking to another
   greproxy, not other GRE devices.)
 - Can also work as a Linux tun device, instead of proxying to GRE.
 - IPv6.
