How to tell if a binary is universal?


cocoa love
Hi, i'm writing several apps and have downloaded XCode 2.1, and have compiled some apps as universal binaries. The problem is how can you tell if the binary is universal or not? Here it says all you have to do is get info on the application, but the extra text that says "Architecture: Intel, PowerPC" doesn't appear to be working on my PowerPC based computer. Any thoughts?
