description         Open source OCR engine

long_description    This package contains an OCR engine - libtesseract and a \
                    command line program - tesseract. Tesseract 4 adds a new \
                    neural net (LSTM) based OCR engine which is focused on line \
                    recognition, but also still supports the legacy Tesseract \
                    OCR engine of Tesseract 3 which works by recognizing \
                    character patterns.
