  21   This module provides a widget, PsppireSelector derived from
  22   GtkButton.
  23
  24   It contains a GtkArrow, and is used for selecting objects from a
  25   GtkTreeView and putting them into a destination widget (often
  26   another GtkTreeView).  Typically this is used in psppire for
  27   selecting variables, thus:

  53   The Source Widget is always a GtkTreeView.  The Dest Widget may be a

  55   supported in the future).
