#############################################################################################
###       This Dockerfile build from source code: Poppler, Leptonica and Tesseract.       ###
###      In this way, you can set the desired versions (even the most recent ones).       ###
###                                                                                       ###
###   With 'curl' command, if you have TLS issues, use '--no-check-certificate' option.   ###
