Copyright for foptions source package in Xenial

This is the Debian GNU/Linux r-cran-foptions package of fOptions, a
set of functions for pricing and hedging various types of financial
options, and part of Rmetrics, a collection of packages for financial
engineering and computational finance. Both fOptions and Rmetrics were
written and compiled primarily by Diethelm Wuertz, with code by others
(see below for fOptions).

This package was created by Dirk Eddelbuettel .
The sources were downloaded from 
	http://www.rmetrics.org
and are also available from
	http://cran.r-project.org/src/contrib/
and all CRAN mirrors as e.g.
	http://cran.us.r-project.org/src/contrib/

The package was renamed from its upstream name 'fOptions' to
'r-cran-foptions' to fit the pattern of CRAN (and non-CRAN) packages
for R.
