Scheduled tasks

We normally write and execute scheduled tasks with Django management commands, which are executed on the command line.

The tasks

• django-admin publish_scheduled_pages - every 10 minutes or more often. This is necessary to make publishing scheduled pages work.
• django-admin clearsessions - once a day (not necessary, but useful).
• django-admin update_index - once a day (not necessary, but useful to make sure the search index stays intact).
