30  * Standard workbench wizard for importing resources from the local file system
31  * into the workspace.
32  * <p>
33  * This class may be instantiated and used without further configuration;
34  * this class is not intended to be subclassed.
35  * </p>
36  * <p>
37  * Example:
38  * <pre>
39  * IWizard wizard = new FileSystemImportWizard();
40  * wizard.init(workbench, selection);
41  * WizardDialog dialog = new WizardDialog(shell, wizard);
42  * dialog.open();
43  * </pre>
44  * During the call to <code>open</code>, the wizard dialog is presented to the
45  * user. When the user hits Finish, the user-selected files are imported
46  * into the workspace, the dialog closes, and the call to <code>open</code>
47  * returns.
48  * </p>
