Syslog is a terrible and loosely defined protocol. Many devices and programs do not conform to it and so their packets may not be parsed correctly by this interpretation, nor may the packets generated by this necessarily be recognized by other devices or programs ;)
This is probably wrong and buggy, and i know the code is ugly, thanks.
Good luck.
- Update to more closely map to the ruby
syslog
API where possible
