6 Package Manager - Abstacts the package manager
7
8 Three steps are
9 - Aquiration of archives (stores the list of final file names)
10 - Sorting of operations
11 - Invokation of package manager
12
13 This is the final stage when the package cache entities get converted
14 into file names and the state stored in a DepCache is transformed
15 into a series of operations.
16
17 In the final scheme of things this may serve as a director class to
18 access the actual install methods based on the file type being
19 installed.
