 * Insert table of contents:


 * Create some pages, assign labels to them and insert a table of contents at


 * the beginning of the document


 *


 * Pages are created in a different chronological order than the order in


 * which they appear in the document. Using page groups create several pages


 * and provide them with page labels. After creating the last page, go back


 * to the start of the document and insert the pages for the table of contents.


 *


 * Required software: PDFlib Lite/PDFlib/PDFlib+PDI/PPS 7


 * Required data: none
