  44 A Gauge is a horizontal or vertical bar which shows a quantity in a graphical
  45 fashion. It is often used to indicate progress through lengthy tasks, such as
  46 file copying or data analysis.
  47
  48 When the Gauge is initialized, it's "complete" value is usually set; at any rate,
  49 before using the Gauge, the maximum value of the control must be set. As the task
  50 progresses, the Gauge is updated by the program via the <code>SetValue</code> method.
  51
  52 This control is for use within a GUI; there is a seperate ProgressDialog class
  53 to present the same sort of control as a dialog to the user.
