Cocoa Foundation/com.webobjects.foundation

...or "how sorting an NSArray made me go bald".

Has anyone written a guide to the differences between Cocoa's  
Foundation and the WO not-quite-variant?  A quick guide to the  
changes would probably fix most of the scrapes I get myself into;  
such as where Comparable/Comparator/NSComparators are used instead of  
functions, where java.lang classes get used instead of Foundation  
equivalents and so on.

Cheers,

Graham.
