/* Standard wizard page for a single file letting the user choose name
 * and path. Looks similar to FileWizardPage, but provides additional
 * functionality:
 * - Description label at the top for displaying introductory text
 * - It does on the fly validation (connected to changed()) and displays
 *   warnings/errors in a status label at the bottom (the page is complete
 *   when fully validated, validatePage() is thus not implemented).
 *
 * Note: Careful when changing projectintropage.ui. It must have main
 * geometry cleared and QLayout::SetMinimumSize constraint on the main
 * layout, otherwise, QWizard will squeeze it due to its strange expanding
 * hacks. */
