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.
