Re: branching much easier, tagging much harder?

Nathaniel, what Michael is doing is to move a tag for a changed file.
This is a very convenient feature when you have modified just a
handful of files for the Release and all (s)he needs to do is to move
tags for those particular files to the RC tag. There are multiple ways
to do it in subversion, but all of them require at least two steps
(merge and commit to tag, remove and add file to tag etc)
