23  * Standard workbench wizard for exporting preferences from the workspace
24  * to the local file system.
25  * <p>
26  * This class may be instantiated and used without further configuration;
27  * this class is not intended to be subclassed.
28  * </p>
29  * <p>
30  * Example:
31  * <pre>
32  * IWizard wizard = new PreferencesExportWizard();
33  * wizard.init(workbench, selection);
34  * WizardDialog dialog = new WizardDialog(shell, wizard);
35  * dialog.open();
36  * </pre>
37  * During the call to <code>open</code>, the wizard dialog is presented to the
38  * user. When the user hits Finish, the user-selected workspace preferences
39  * are exported to the user-specified location in the local file system,
40  * the dialog closes, and the call to <code>open</code> returns.
41  * </p>
