  The data set \code{euro} contains the value of 1 Euro in all
  currencies participating in the European monetary union (Austrian
  Schilling ATS, Belgian Franc BEF, German Mark DEM, Spanish Peseta ESP,
  Finnish Markka FIM, French Franc FRF, Irish Punt IEP, Italian Lira
  ITL, Luxembourg Franc LUF, Dutch Guilder NLG and Portugese Escudo

  the respective rate and round to 2 digits.

  The data set \code{euro.cross} contains conversion rates between the
  various Euro currencies, i.e., the result of
  \code{outer(1 / euro, euro)}.
