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.
