/* ######################################################################
Acquire Item - Item to acquire
Each item can download to exactly one file at a time. This means you
cannot create an item that fetches two uri's to two files at the same
time. The pkgAcqIndex class creates a second class upon instantiation
to fetch the other index files because of this.
