Video Scheduler.

Usage:        {$script} [OPTIONS]
Example:      {$script} 

All arguments are long options.

  -h, --help  This page.

  -r, --root  Set the working directory for the script to the specified path.
              To execute Drupal this has to be the root directory of your
              Drupal installation, f.e. /home/www/foo/drupal (assuming Drupal
              running on Unix). Current directory is not required.
              Use surrounding quotation marks on Windows.
  
  -s, --site  Used to specify with site will be used for the upgrade. If no
              site is selected then default will be used.
  
  -v, --verbose This option displays the options as they are set, but will
              produce errors from setting the session.

To run this script without --root argument invoke it from the root directory
of your Drupal installation with

  ./{$script}
