/**
 * Flatfile CLI tool.
 *
 * Notes:
 *   - it is required to use the web server account when executing PHP CLI scripts
 *   - you need to change the "www-data" to match the apache user account
 *   - use "su" if "sudo" not available
 *
 * Update
 *
 * This plugin now has a enrolment sync scheduled task. Scheduled tasks were
 * introduced in Moodle 2.7.  It is possible to override the scheduled tasks
 * configuration and run a single scheduled task immediately using the
 * admin/tool/task/cli/schedule_task.php script. This is the recommended
 * method to use for immediate enrollment synchronisation.
 *
 * Usage help:
 * $ php admin/tool/task/cli/schedule_task.php -h
 *
 * Execute task:
 * $ sudo -u www-data /usr/bin/php admin/tool/task/cli/schedule_task.php /
 * --execute=\\enrol_flatfile\\task\\flatfile_sync_task
 *
 * @package    enrol_flatfile
