+scanned pages.  It performs operations such as page splitting, deskewing,
+adding/removing borders, and others.  You give it raw scans, and you get pages
+ready to be printed or assembled into a PDF or DJVU file.  Scanning, optical
+character recognition, and assembling multi-page documents are out of scope of
+this project.
+
+Scan Tailer Advanced is a fork of Scan Tailer that merges Scan Tailor Featured
+and Scan Tailor Enhanced versions as well as including many more bug fixes.")
