+   Package Manager - Abstacts the package manager
+
+   Three steps are 
+     - Aquiration of archives (stores the list of final file names)
+     - Sorting of operations
+     - Inokation of package manager
+   
+   This is the final stage when the package cache entities get converted
+   into file names and the state stored in a DepCache is transformed
+   into a series of operations.
+
+   In the final scheme of things this may serve as a director class to
+   access the actual install methods based on the file type being
+   installed.
