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
+ - 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
