Copyright for cairodevice source package in Focal

This is the Debian GNU/Linux r-cran-cairodevice package of
cairoDevice, a Cairo/Gtk2 device drive for GNU R, which was written by
Lyndon Drake and Michael Lawrence.

This package was created by Dirk Eddelbuettel .
The sources were downloaded from 
	http://www.ggobi.org/RGtk2
The sources are expected to eventually be available at CRAN
	http://cran.r-project.org/src/contrib

The package was renamed from its upstream name 'cairoDevice' to
'r-cran-cairodevice' to fit the pattern of CRAN (and non-CRAN)
packages for R, given that the package is expected to be available
from CRAN in the near future.
