# Description:
    # This tool will automatically check your python's pip list in your system,
    # and update all packages to their newest versions.
    # Then it will display a summary, with double checking points
    # (number of packages before update compared to after update;
    # and the number of packages that have been updated). Then it will display
    # the list of updated packages: New Versions vs. Old versions.
