Acquire Item - Item to acquire
When an item is instantiated it will add it self to the local list in
the Owner Acquire class. Derived classes will then call QueueURI to
- register all the URI's they wish to fetch for at the initial moment.
+ register all the URI's they wish to fetch at the initial moment.
Two item classes are provided to provide functionality for downloading
of Index files and downloading of Packages.
+ A Archive class is provided for downloading .deb files. It does Md5
+ checking and source location as well as a retry algorithm.
