gscan2pdf 2.3.0-1 (amd64 binary) in ubuntu disco

 Only five clicks are required to scan several pages and then save all or a
 selection as a PDF or DjVu file, including metadata if required.
 .
 gscan2pdf can control flatbed or sheet-fed (ADF) scanners with SANE via
 libimage-sane-perl, scanimage or scanadf, and can scan multiple
 pages at once. It presents a thumbnail view of scanned pages, and permits
 simple operations such as cropping, rotating and deleting pages.
 .
 OCR can be used to recognise text in the scans, and the output
 embedded in the PDF or DjVu.
 .
 PDF conversion is done by PDF::API2.
 .
 The resulting document may be saved as a PDF, DjVu, multipage TIFF file, or
 single page image file.
