6 Acquire Item - Item to acquire
7
8 When an item is instantiated it will add it self to the local list in
9 the Owner Acquire class. Derived classes will then call QueueURI to
10 register all the URI's they wish to fetch for at the initial moment.
11
12 Two item classes are provided to provide functionality for downloading
13 of Index files and downloading of Packages.
