-overview = """\
-This class encapsulates a monochrome mask bitmap, where the masked area is black
-and the unmasked area is white. When associated with a bitmap and drawn in a device
-context, the unmasked area of the bitmap will be drawn, and the masked area will
-not be drawn.
-
-This example shows not only how to create a Mask, but the effects of the Device
-Context (dc) <code>Blit()</code> method's logic codes.
