How to start rsync daemon at boot

[Jamie]

I have an i386 installed of Ubuntu 6.06 and I want to have an rsync daemon
start at boot time but despite much Googling, reading of man pages and
general seeking stuff out I cannot find a way to do this.
Only thing of use I found was something telling me to add a line to inetd
or xinetd to run it, but as neither of these files exist on my system I
don't think that's a viable option.
Can someone please help me out here.

Thanks

Jamie
