File Attachments
An attachment is a way of including one or more files (of any type) within a PDF docu-
ment. Files may be attached to the document as a whole, or to individual pages. Typ-
ically, the PDF viewer will display a list of any attachments, allowing the user to open
or save them. This facility could be used, for example, to bundle example resources
along with a PDF of a slide-show presentation.
