Local replica of JAliEn central services for research and development

In preparation of LHC's next run, CERN has been developing JAliEn, a successor to their current grid computing middleware, AliEn. To ease development and give individual developers a robust local development framework with all necessary capabilities, the core of the JAliEn system (JCentral) must be deployed individually, on a single host, with all necessary configurations. Therefore the project aims to develop a command line utility for JAliEn developers to quickly start, develop and teardown JCentral replicas locally.
