Way to listen in on all Apple Events?

I'm looking for a way to listen in to all Apple Events send by any program to any other program. There was an ap开发者_如何学运维p, AEMonitor, that used to do this but it is abandonware as of now.

Is there a known way to do this via cocoa, carbon, etc?

Any help MUCH appreciated.

Carification: I'm looking to monitor ALL apple events or at very least a lion share of them. I am aware that it is possible to launch an app and listen to its AEs like this.

From what I recall of AEMonitor (which I occasionally miss), it required the relaunch of the target application. I'd bet that it was setting the environment variables that are linked to in the macosxhints.com article.
