  xsane2tess converts files to TIF, scans them with TesseractOCR
  and outputs the text in a file.
  OPTIONS:
    -i   define input file (any image-format supported)
    -o   define output-file (*.txt)
    -l   define language-data tesseract should use
  Progress- & error-messages will be stored in this logfile:
     $TEMP_DIR$ERRORLOG
  xsane2tess depends on
    - ImageMagick  http://www.imagemagick.org/
    - TesseractOCR http://code.google.com/p/tesseract-ocr/
