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 | |
6fc33863 | 11 | - Invokation of package manager |
6c139d6e AL |
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. | |
