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