   6    Acquire Item - Item to acquire
   7
   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.
