+/**
+ * Progress bars visually display the status of an operation, such as a download,
+ * and can be either determinate or indeterminate:
+ *
+ * - **determinate** process bars show the percent of an operation that is complete.
+ *
+ * - **indeterminate** process bars use a visual display of motion to indicate that an operation
+ *   is taking place. Because the extent of an indeterminate operation is unknown, the bar does
+ *   not use percentages.
+ *
+ * The value of the `progress` configuration determines whether the bar is determinate or indeterminate.
+ *
+ *     @example
+ *     // Examples of determinate and indeterminate progress bars.
+ *     var progressBar1 = new OO.ui.ProgressBarWidget( {
+ *         progress: 33
+ *     } );
+ *     var progressBar2 = new OO.ui.ProgressBarWidget();
+ *
+ *     // Create a FieldsetLayout to layout progress bars
+ *     var fieldset = new OO.ui.FieldsetLayout;
+ *     fieldset.addItems( [
+ *        new OO.ui.FieldLayout( progressBar1, {label: 'Determinate', align: 'top'}),
+ *        new OO.ui.FieldLayout( progressBar2, {label: 'Indeterminate', align: 'top'})
+ *     ] );
+ *     $( 'body' ).append( fieldset.$element );
+ *
+ * @class
+ * @extends OO.ui.Widget
+ *
+ * @constructor
+ * @param {Object} [config] Configuration options
+ * @cfg {number|boolean} [progress=false] The type of progress bar (determinate or indeterminate).
+ *  To create a determinate progress bar, specify a number that reflects the initial percent complete.
+ *  By default, the progress bar is indeterminate.
