title: Can I create a subversion branch that tracks trunk?
body: <p>I would like to create a branch of one of the modules in my SVN repository.  This module contains several sub-modules.  I would like some of these sub-modules to be divergent in the branch, but other sub-modules should maintain consistency with trunk.</p>
  
  <p>So, for example, sub-module A should be divergent between BRANCH and TRUNK, but sub-module B should not.  A change committed to A in BRANCH will not appear in TRUNK, but a change committed to B in BRANCH will automatically be reflected in TRUNK.  I'd like this to happen automatically, without me having to force relevant changes from BRANCH into TRUNK.</p>
  
  <p>Is this something that is possible to do using subversion?</p>
