[syslog-ng] syslog-ng and windows

Hello, I'm using syslog-ng as a central log server, and I have both linux and windows clients. I know that there are some syslog windows clients ( NTsyslog, snare) but I can't find any open source syslog-ng clients. What I'm looking for is (at least if it does not exist) information on the TCP data format used by syslog-ng. So I could write a little udp to tcp syslog translator that could be used on windows clients (and maybe modify NTsyslog if I have enought time...) Thanks JF
