sometimes there several version exist of same port e.g. 
	
	
	
		
 or other...
is there any (reliable or not) source in internet where we can find what ports to use best or is there automated utility that can scan it and upgrade all old ports to stable or release/experimental etc or just warn about outdated (that's not mainline) ports installed (ports still can be present in ports tree..)?
Any guidelines or faq for this?
UPDATING is only source...?
