-"""Color chip megawidget.
-This widget is used for displaying a color.  It consists of three components:
-
-    label -- a Tkinter.Label, this is the chip's label which is displayed
-             about the color chip 
-    chip  -- A Tkinter.Frame, the frame displaying the color
-    name  -- a Tkinter.Label, the name of the color
-
-In addition, the megawidget understands the following options:
-
-    color -- the color displayed in the chip and name widgets
-
-When run as a script, this program displays a sample chip.
