Hi, I'm currently working on bug 904029, support for POSIX parameters and values in engine-manage-domains. I think there are two possible solutions: 1) Write custom parser (similar to EngineConfigCLIParser used for engine-config) 2) Add CLI parsing library to project and use it for all command line clients (first implementation could be for engine-manage-domains) I think 2) is much better approach, but I'm not sure about the process of adding new library to project. Personally I like JCommander ( http://jcommander.org ), using annotation for parameter specification is great. JCommander is licensed with Apache 2.0 license, so the addition shouldn't be a problem. So, would it be possible to add JCommander library to project? Martin Perina
