I said before and I'll say again: you're making assumptions about what branches are based on some model that doesn't fit reality. If Subversion does not support your workflow, then replace Subversion, or change your workflow. Stop insisting that your definition of a branch is a universal truth. -- Brane -- Branko Čibej Director of Subversion | WANdisco | www.wandisco.com
