[Building Sakai] How we tag releases

[Noah Botimer]

I've been thinking about these hollow parts of the repository for  
some time. I think the right way to do this is to materialize our  
tags, but not branches. It's actually not that hard. Here's an abstract.

  1. Figure out which externals and revisions are to be used.
  2. Check out the top tags dir with svn co -N /sakai/tags.
  3. Create an svn dir for the new tag locally.
  4. Run through the externals and svn cp from the branches to the  
working copy.
  5. Check the whole working copy in.

The biggest benefit, in my mind, is that the tags become cohesive  
snapshots of everything that would make the release artifacts.  
Another benefit is that this would give a single commit tag, rather  
than assembling from a number of revs. We could also individually tag  
the projects and copy those in, rather than from branches, if folks  
really use individually project tags. This wouldn't change the net  
effect.

Thanks,
-Noah
