You find it in Mac OS X's DevTools documentation listed under Cocoa,  
language Obj-C and with a parent of NSObject. Clicking on the entry  
gives you almost the same description as NSObject's -isEqual:.

Nearer observations shows, however, it's a method/function of Cocoa's  
scripting suite. My foul, sorry for the noise.

This makes at least _some_ sense. :-)


Thanks,
