Prefpane updates your wireless network location automatically.

Have you ever wished that your Mac would update its location automatically on the basis of the network that you're currently connected to? Perhaps you use your Mac at work accessing the internet though a proxy server, and also at home where you have none. It isn't difficult to select a new location from the Location menu in the Apple menu, but why should you have to? Locamatic will do all this for you! Now on version 2, it’s Leopard compatible and it can also set your default printer and your default home page.
