overview = """\
A status bar is a narrow window that can be placed along the bottom of
a frame to give small amounts of status information. It can contain
one or more fields, one or more of which can be variable length
according to the size of the window.  

This example demonstrates how to create a custom status bar with actual
gadgets embedded in it. In this case, the first field is just plain text,
The second one has a checkbox that enables the timer, and the third
field has a clock that shows the current time when it is enabled.
