6 | Acquire Item - Item to acquire | |

8 | Each item can download to exactly one file at a time. This means you | |
9 | cannot create an item that fetches two uri's to two files at the same | |
10 | time. The pkgAcqIndex class creates a second class upon instantiation | |
11 | to fetch the other index files because of this. | |
