Then a private development branch may just be the right thing for you to use.
Bazaar is a distributed version control system. The most important difference to CVS or to subversion is that it separates the procedure of making commits and the procedure of publication (called push in Bazaar) and retrieval (pull) patches to/from a remote location. A commit is always made locally to your copy of the branch (if you created a branch). If you want to publish your modifications you need to @em push it somewhere.
If you want to merge with your parent branch you need to push your changes back to the parent branch, i.e. the one you originally branched from. If you want to make it available to other users, but you do not want to merge simply push your branches to another location. If there would be conflicts, then Bazaar will inform you and suggest that you do a @em merge.
By default the modules included in the openWNS SDK are already private branches. Each of the module is a full copy of its including all its history information. In fact, you do not need to create a private branch - you already have one.
