18
 * Flatfile CLI tool.
19
 *
20
 * Notes:
21
 *   - it is required to use the web server account when executing PHP CLI scripts
22
 *   - you need to change the "www-data" to match the apache user account
23
 *   - use "su" if "sudo" not available
24
 *
25
 * Update
26
 *
27
 * This plugin now has a enrolment sync scheduled task. Scheduled tasks were
28
 * introduced in Moodle 2.7.  It is possible to override the scheduled tasks
29
 * configuration and run a single scheduled task immediately using the
30
 * admin/cli/scheduled_task.php script. This is the recommended
31
 * method to use for immediate enrollment synchronisation.
32
 *
33
 * Usage help:
34
 * $ php admin/cli/scheduled_task.php -h
35
 *
36
 * Execute task:
37
 * $ sudo -u www-data /usr/bin/php admin/cli/scheduled_task.php /
38
 * --execute=\\enrol_flatfile\\task\\flatfile_sync_task
39
 *

 * @package    enrol_flatfile
