Rule sets and how to use them...

Looking at rule sets, they appear to be conceptually cool, but damned if I can figure out how to actually get them to do anything.

What I would have expected from the description is that:

1. You define a rule set (effectively writing a subroutine).
2. You then connect that rule set with an event trigger of some kind.
3. When the even happens, the rule set gets triggered.

But that doesn't seem to be the way it works.

I've installed rules, created a rule set and would love to figure out how to trigger the thing. Pointers to the right place in the documentation would be acceptable (or a quick explanation).

I can get the same effect through multiple rules, but that's kind of like programming a neural net. If you don't get everything absolutely in the right order, strange things can happen.

Or are rule sets really, really just for scheduling and not for "interactive" use?

Thanks,
