Jmol selections
=================

Write :class:`MDAnalysis.core.groups.AtomGroup` selection to a `str` file
that defines a `Jmol selection`_. To be used in Jmol_ like this::

  script macro.spt
  select ~selection

The selection is named *mdanalysis001*.TODO

.. autoclass:: SelectionWriter
   :inherited-members:
