There is no real rush, but it sounds like we should all meet at some point to discuss the best integration-migration roadmap; on the feature side, the adaptation of Chapter 4 of the LiE manual to Sage is a great basis for this road map. Then, we could start with a documented interface between LiE and Sage. Later, if there is a clear roadmap to be followed, one can plan that the Sage developers involved in the root system stuff will progressively integrate/port the material on a need-driven basis. David: would you by any chance be interested in taking over the maintenance of the LiE package for Sage, and integrate there your Cython interface? As far as I can tell, the current minimal version was created a while ago by William and Michael. It should not be that much work, especially with Marc's support in case of technical issue with LiE.
