Copyright for fextremes source package in Jammy

This is the Debian GNU/Linux r-cran-fextremes package of fExtremes, a
set of functions for modelling extreme value, and part of Rmetrics, a
collection of packages for financial engineering and computational
finance. Both fExtremes and Rmetrics were written and compiled primarily
by Diethelm Wuertz, with code by others (see below for fExtremes).

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 'fExtremes' to
'r-cran-fextremes' to fit the pattern of CRAN (and non-CRAN) packages
for R.
