+Circle Example
+==============
+
+This example exercises circle (ellipse) drawing.  You should see sliders at the
+top of the screen with the Kivy logo below it.  The sliders control the
+angle start and stop and the height and width scales.  There is a button
+to reset the sliders.   The entire example is coded in the
+kv language description.
