General plugins

This simple standalone command is for hiding/showing a module (activity or resource) in a Moodle course.
If the URI of the module (assignment, chat, forum, quiz, page, ...) you want to hide/show is like
http://moodle.server.name/mod/quiz/view.php?id=34, you can hide it by
  php set_coursemodule_visible.php 34 0
and show it by
  php set_coursemodule_visible.php 34 1

You can set the commands in crontab for time-dependent frequent access control of an activity or resource.
