/**
==============================================================================
* 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.
