 """
 A backwards compatibility layer for IPython.Shell.
 
 Previously, IPython had an IPython.Shell module.  IPython.Shell has been moved
 to IPython.core.shell and is being refactored.  This new module is provided
 for backwards compatability.  We strongly encourage everyone to start using
 the new code in IPython.core.shell.
