"""
This is the h5py completer extension for ipython. It is loaded by
calling the function h5py.enable_ipython_completer() from within an
interactive IPython session.
It will let you do things like::
f=File('foo.h5')
f['<tab>
# or:
f['ite<tab>
which will do tab completion based on the subgroups of `f`. Also::
f['item1'].at<tab>
will perform tab completion for the attributes in the usual way. This should
also work::
a = b = f['item1'].attrs.<tab>
as should::
f['item1/item2/it<tab>
