::0.5
Added Francesco Prelz's option handling patch for clearing the preferred-time of a rouge prefix.

::0.4
More overhaul of the logging. Messages have a syslog-like priority. Error messages go to syslog and the log file. Introduction of `mac' matches in rules. Fixed the lack of SIG_CHLD handling.

::0.3
Includes Eric Vyncke's syslog code, and his friendly-error-handling when importing the config file.

::0.2
Moves packet injection code to libpcap, instead of poking the kernel directly. 
This version now works under FreeBSD 7
