grasp-manager is a script placed in the root folder of grasp. It contains useful tools for users, explained in the user documentation (section in progress), but it also contains many useful tools to help developers. GRASP code is organized in many repositories and this tool will help to keep all of them synchronized: changing branches, pushing them to remote server, etc. at the same time.
[ Section in progress: all actions which can be done by grasp-manager for developers, should be documented here ]
