u option for ar

[Dave Mitchell]

I am in need of information on the ar command. I am updating documentation and
there is none for the u option with ar. I have used ar with the u option but
couldn't determine what it does. The source code wasn't a help either. If anyone
knows what it does and if there is any documentation available, your help would
be appreciated.
