Renaming a port

[Ryan Schmidt]

What's the procedure if I want to rename a port? I've been meaning to  
install ViewVC on my Mac since forever, and now that I finally have  
some free time, I thought I'd give it a shot, and realized it would  
be good to have a port for it. And in fact there is a port for  
ViewCVS, the old name of ViewVC, but it's old and not maintained. I'd  
like to try to update it, but the first step would be to rename it  
from viewcvs to viewvc. Do I just "cd dports/devel && svn mv viewcvs  
viewvc" or should we keep the viewcvs port around with a note about  
the name change? I note that the ethereal port still exists even  
though that project has been renamed wireshark. What's the  
recommended way to handle this situation? Is it documented somewhere?
