Keeping local modifications

[Kent Karlsson]

Hey,

I'm keeping some local modifications to some portfiles to keep them  
working with a bunch of local modifications to the system. In order to  
do this, I copy the ports I modify to a local dports dir and make the  
changes there so they won't be lost when I do a selfupdate.

Is there some way that I can make my locally modified ports totally  
replace the official ones? Just adding a Revision tag makes them  
impossible to distinguish in the list and I also see both versions.

Is anyone else doing this and how do you usually do it?
