Xubuntu 7.04 - system-wide Proxy settings - where?

[David Stubblebine]

So I've installed Ubuntu 7.04 on several older iMacs with few  
problems.  However, I put Xubuntu 7.04 on one and can't find where to  
enter network proxy settings.  Without it I can't download updates,  
etc.  Is there a control panel somewhere or do I have to do it from  
the command line?
