Basically I’d like to have copy-on-write branches.
Meaning that I want files by default to follow the trunk branch, only if I modify the file it gets “locked” to the current branch. So that by running “foo update” I get all the updates, except for where I decided to diverge?

using svn:externals was suggested to me, but it doesn’t do the trick, I need it on a per-file basis. And I’d like to have it automatically, so I can just commit my changes and they’ll end up in my “overlay” repository by default…

I've not used CVS since University. I must confess that in my job I've been using Borland's StarTeam and love it.It is really hard to go back to the command line again.<p/>Sean Very interesting.
