- * STUDENT PUBLICATIONS MODULE
- *
- * Note: for a more advanced module, see the dropbox tool.
- * This one is easier with less options.
- * This tool is better used for publishing things,
- * sending in assignments is better in the dropbox.
- *
- * GOALS
- * *****
- * Allow student to quickly send documents immediately
- * visible on the course website.
- *
- * The script does 5 things:
- *
- * 1. Upload documents
- * 2. Give them a name
- * 3. Modify data about documents
- * 4. Delete link to documents and simultaneously remove them
- * 5. Show documents list to students and visitors
- *
- * On the long run, the idea is to allow sending realvideo . Which means only
- * establish a correspondence between RealServer Content Path and the user's
- * documents path.
- *
- * All documents are sent to the address /$_configuration['root_sys']/$currentCourseID/document/
- * where $currentCourseID is the web directory for the course and $_configuration['root_sys']
- * usually /var/www/html
- *
- * Modified by Patrick Cool, february 2004:
- * Allow course managers to specify wether newly uploaded documents should
- * be visible or unvisible by default
- * This is ideal for reviewing the uploaded documents before the document
- * is available for everyone.
- *
- * note: maybe the form to change the behaviour should go into the course
- * properties page?
- * note 2: maybe a new field should be created in the course table for
- * this behaviour.
- *
- * We now use the show_score field since this is not used.
