From Help when Packager is open(if you can get it open).
package
An icon that represents embedded or linked information.
That information may
consist of a complete file, such as a Paint bitmap, or part of a file, such as
a spreadsheet cell. When you choose the package, the application used to
create the object either plays the object (for example, a sound file) or opens
and displays the object. If you change the original information, linked
information is automatically updated. However, you must manually update
embedded information.
See also: embedded object, linked object, OLE
Do not know what the range of uses would be. Have never had occasion to avail
myself of this feature.
