kReMail will be an app that scans in paper based letters and converts them (using tesseract ocr) to emails, then stores them in akonadi. Still under heavy development.

Requirements
---------------------
KDE libs, KDE pim libs, KDE graphics libs
Tesseract OCR engine - http://code.google.com/p/tesseract-ocr/
Imagemagick (for convert, ugly hack) - http://www.imagemagick.org:80/script/index.php
