"""This is a convenient package to use from Python or IPython interpreter.
It loads the main features of silx and provides high-level functions.

>>> from silx import sx

When used in an interpreter is sets-up Qt and loads some silx widgets.
When used in a `jupyter <https://jupyter.org/>`_  /
`IPython <https://ipython.org/>`_ notebook, neither Qt nor silx widgets are loaded.

When used in `IPython <https://ipython.org/>`_, it also runs ``%pylab``,
thus importing `numpy <http://www.numpy.org/>`_ and `matplotlib <https://matplotlib.org/>`_.
