 """ User configuration file for IPython
 
 This is a more flexible and safe way to configure ipython than *rc files
 (ipythonrc, ipythonrc-pysh etc.)
 
 This file is always imported on ipython startup. You can import the
 ipython extensions you need here (see IPython/Extensions directory).
 
 Feel free to edit this file to customize your ipython experience.
 
 Note that as such this file does nothing, for backwards compatibility.
 Consult e.g. file 'ipy_profile_sh.py' for an example of the things 
 you can do here.
