+This library provides a text mode progressbar. This is typically used
+to display the progress of a long running operation, providing a visual
+clue that processing is underway.
+
+The ProgressBar class manages the progress, and the format of the line
+is given by a number of widgets. A widget is an object that may display
+diferently depending on the state of the progress. There are three types
+of widget: - a string, which always shows itself; - a ProgressBarWidget,
+which may return a diferent value every time it's update method is called;
+and - a ProgressBarWidgetHFill, which is like ProgressBarWidget, except
+it expands to fill the remaining width of the line.
+
+The progressbar module is very easy to use, yet very powerful. And
+automatically supports features like auto-resizing when available.
