  Usage: ${scriptName} [Options]

  This script prepares the update packages to include them
  into pacman repository. This is done by transforming them into separate
  packages which can be migrated to pacman using convert_packages.sh.

  Options:
    -h --help        .. Show this help.
    --folder-prefix  .. Prefix to use for download folder and migrated packages
    --debug                 Show more output and stop after every step to be
                            able to read the output.
