Easy Way to Apply a Patch from Trac?

I see a patch in Trac that I want to try to apply to a frozen copy of Rails
in my app.

I'm on OS X Tiger.

Can anyone point me to a Web site or any resource that could give me a
pointer on applying this diff file?

I've never done it before but I'd like to give it a go.

Best,
Hunter

In a terminal:
patch < foo.diff

You might need to use the -p option. Check the manual:
man patch
