portsnap - overwrite local changes

[Oliver Lehmann]

Hi,

in case I made some local modifications to a ports Makefile.... in the  
past with CVSup it was "easy" to get everything back in-sync by just  
running CVSup. With portsnap fetch update, my modified Makefile stays  
modified. What is the suggested way in syncing my local portstree 1:1  
with the official portstree?

   Greetings, Oliver
