+
+ Package Manager - Abstacts the package manager
+
+ Three steps are
+ - Aquiration of archives (stores the list of final file names)
+ - Sorting of operations
+ - Invocation 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.
