overview = """\
A Gauge is a horizontal or vertical bar which shows a quantity in a graphical
fashion. It is often used to indicate progress through lengthy tasks, such as
file copying or data analysis.

When the Gauge is initialized, it's "complete" value is usually set; at any rate,
before using the Gauge, the maximum value of the control must be set. As the task
progresses, the Gauge is updated by the program via the <code>SetValue</code> method.

This control is for use within a GUI; there is a seperate ProgressDialog class
to present the same sort of control as a dialog to the user.
