automated testing with browsers

Hey,

Does anyone have any code that starts/stops browsers?

I'd like to automate selenium testing by having a process start
firefox (say), tell it to go to
http://test-server/selenium/?auto=true, and then kill the browser when
it's done.

I'm interested in any code/tips to help doing this for firefox, opera,
safari, and IE.

Cheers,
Luke
