2008-05-29 13:14 AEST by Arthur Barrett - If a person wants to create a workspace/sandbox based on that 'may_release' but 
wants to 'add' the updated files tagged with 'patch1' (not a recommended 
strategy' then it is not possible without using 'merge', ie:
  cvs co -r may_release devel
  cd devel
  cvs up -j patch1

This can be a problem since it is not then possible for the build tool to 'tag' 
these versions with a build number.

What would be ideal is if 'update -f' could take an optional parameter for an 
alternative to 'HEAD', ie:
cvs up -f may_release -r patch1
