How do you merge a tag with a branch

I have a question about SVN,

I would like to merge a tag lets say: http://my.dev.com/svn/proj/tags/v.3.1.2 with my w开发者_如何学Pythonorking copy. What is the svn command for that

Thanks

SVN doesn't assign any special meaning to tags or to branches, they are just a convention for repository layout. As far as SVN is concerned, they are just "copies" of particular revisions (provided you have been managing your repository according to this convention). You should be able to merge a tag just like you would merge a branch.

Why would you want to merge a "Tag", you probably mean a Branch.
