 * PDF portfolio starter:

 * Package multiple PDF and other documents into a PDF portfolio

 * The generated PDF portfolio requires Acrobat 9 for proper

 * viewing. The documents in the Portfolio will be assigned predefined

 * and custom metadata fields; for the custom fields a schema description

 * is created.

 *

 * Acrobat 8 will only display a "PDF package" with a flat list of documents

 * without any folder structure.

 *

 * Required software: PDFlib/PDFlib+PDI/PPS 8

 * Required data: PDF and other input documents
