How to write a string

[Christopher Culver]

I have a feeling that this will have a painfully obvious answer, but 
after looking through the API I'm still not sure how to do this.

I have a string, NSString *aString. How do I put this string on the 
pasteboard? Must I initialise an NSPasteboard and write to it (which 
Cocoa docs seem to suggest), or can I just pass a message to NSApp? 
In any event, please let me know the code necessary.
