Creating a new pb version

• Ensure that all dev tests are ok first ;-) cd pb
• Ensure that the SVN status is correct for both devel and pbconf: svn up
• Ensure that the Changelogs are OK for all packages: cd devel svn log pkg gvim ../pbconf/devel/*/pbcl
• Use pb to create the target version from the devel branch: pb -p pb -r devel -V 0.15.1 newver
• Edit again the pbcl files for the new version 0.15.1 and remove mentions of new version gvim ../pbconf/0.15.1/*/pbcl svn ci
• Edit the config file to declare the version stable (delivery and testver): gvim ../pbconf/0.15.1/pb.yml svn ci
• Build a test version in a ctn: pb -p pb -r 0.15.1 -m centos-7-x86_64 sbx2ve
• Build for all ctns: pb -p pb -r 0.15.1 sbx2ve
