e Casida ansatz for excited states in linear-response
 theory. If you set <tt>TDOutput</tt> to contain <tt>populations</tt>, you may ask for these approximated
 populations for a number of excited states, which will be described in the files specified
 in this block: each line should be the name of a file that contains one excited state.

 FIXME: description of the format of the files.
