0.9.5 -- Nov 27 2001
- updated online help
- added --comp=algo to choose the compression algorightm function used
  to compress the packet
- DoS resistance: Changed the default udp port allocation. if the port 
  is unspecified, yavipin allocate a random unused one (using 
  /dev/urandom), it increase the DoS resistance. the additionnal
  security will likely be canceled if the initiator is behind a NAT box.
  o added ":dynamic" while specifiing udp port. It forces yavipin to use
    the kernel udp port allocation (aka make it easy to predic). 
    it SHOULD not be used. it is an debug option
- configuration: simplified the address binding. the only requirement
  is to specify the destination address for a initiator. all the other
  cases may be done automatically if the admin doesnt explicitly specify
  them.

0.9.2 -- Nov 16 2001
- for forward secrecy, periodically renew the diffie hellman secret
  o even if the attacker cracks the box, he won't be able to read
    traffic older than YAV_AUTH_NEW_DH_PRIV (as skey renewal is shorter)
  o the period is YAV_AUTH_NEW_DH_PRIV (default 10min)
- update the web docs
- use the libc daemon() instead of my own
- source beautifullication (rename cert by auth)
