  13 This script will download the current Oracle spoiler in full from the Gatherer
  14 online database (http://ww2.wizards.com/gatherer/index.aspx) and format it as a
  15 flatfile database for use with Mindless Automaton. The filename will be
  16 generated of the form 'oracle-MMddYYYY.txt', and a symlink 'oracle.txt' will be
  17 created.
