Lots of work on exception handling, including tests for traceback printing. We finally have some tests for various exception mode printing, via doctests that exercise all three modes! Also changed handling of sys.exit(X) to only print the summary message, as SystemExit is most often a 'handled' exception. It can still be 100% silenced via '%run -e', but now it's much less intrusive. Added a new %tb magic to print the last available traceback with the current xmode. One can then re-print the last traceback with more detail if desired, without having to cause it again.

      """Asynchronous clients for the IPython controller.

      This module has clients for using the various interfaces of the controller 

      in a fully asynchronous manner.  This means that you will need to run the

      Twisted reactor yourself and that all methods of the client classes return

      deferreds to the result.

      The main methods are are `get_*_client` and `get_client`.
