    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.
