echo ║ This script will take in your Python scripts and the requirements  ║
echo ║ file and turn them into a stand-alone BAT file that can be shared. ║
echo ║                                                                    ║
echo ║ The output BAT file will check for Python and install it, if it is ║
echo ║ missing. After that it will re-create the original Python and      ║
echo ║ requirement.txt files along with a starter and optional timer.     ║
echo ║                                                                    ║
echo ║ The purpose is to bypass EXE blocking and other security measures. ║
echo ║ Optionally the output can be a TXT file so that the sharing of BAT ║
echo ║ files can be avoided.                                              ║
