# ellipsizing.py - Simple example to demonstrate the usage of
#                  exo.EllipsizedLabel and exo.CellRendererEllipsizedText,
#                  which provide text ellipsizing support for Gtk 2.4,
#                  which also works with Gtk 2.5 and above without the
#                  need to change your code.
