I hope there is some easy way to get a list starting from the > jonas or eclipse-platform package. I've generally written scripts to query the rpm database and/or a directory full of rpms and emit graphviz files for printing. Generally the scripts will start with a package at the top of the tree (tomcat5-admin-webapps, for example, or lately jonas-examples) and work their way down through whatever set of dependencies I was interested in and ignoring whatever set of things I didn't want to see. I attached an example, so you can see what I mean. If I recall, it draws a graph of the runtime dependencies of the packages I maintain in FC4, with subpackages treated as separate entities. Hope that helps, Gary
