"""A class to manage IPython extensions.
An IPython extension is an importable Python module that has
a function with the signature::
def load_ipython_extension(ipython):
# Do things with ipython
This function is called after your extension is imported and the
currently active :class:`InteractiveShell` instance is passed as
the only argument. You can do anything you want with IPython at
that point, including defining new magic and aliases, adding new
components, etc.
The :func:`load_ipython_extension` will be called again is you
load or reload the extension again. It is up to the extension
author to add code to manage that.
You can put your extension modules anywhere you want, as long as
they can be imported by Python's standard import mechanism. However,
to make it easy to write extensions, you can also put your extensions
in ``os.path.join(self.ipython_dir, 'extensions')``. This directory
is added to ``sys.path`` automatically.
