Incrementing the development version

As last step you have to increment the version number to the next development release number. Before doing that you should make sure that you have merged the released software version into the devel branch. You do this by typing:

$ git checkout devel
$ git merge master

Now you launch again the release manager to update the version number:

$ dev/release.py
