edu_file_upload_widget   db   class_id   folder_name   { default_read "" }   { default_write "ta" }   { version_notes_p "t" }

This produces the widget that takes care of the file permissions for classes. It assumes that it is within a table and returns HTML that will fill in two rows of the two column table. An empty string for a role means that public has that permission
