- * 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
- *
- * 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.
- *
