+is a modified and extended version of Albrecht Gebhardt's build script
+ http://www.math.uni-klu.ac.at/~agebhard/build-R-contrib-debs.pl
+The package sources were downloaded from
+ http://cran.us.r-project.org/src/contrib/
+and should also be available on any other mirror of http://cran.r-project.org.
+
+The package was renamed from its upstream name \'$pkg->{Package}\' to \'r-cran-$pkg->{DebName}\'
+to fit the pattern of CRAN packages for R.
+
+The Copyright, as asserted in the DESCRIPTION file, is:
+$license
+
+On a Debian GNU/Linux system, common licenses are included in the directory
+/usr/share/common-licenses/.

+r-$pkg->{Repository}-$pkg->{DebName} for Debian
+
+This Debian package was created from sources on the
+$repository site, accessible at
+${repository_url}.
+
+The package was built using the script cran2deb, which was derived from
+ http://www.math.uni-klu.ac.at/~agebhard/build-R-contrib-debs.pl
+by Albrecht Gebhard. This script is now maintained by the pkg-bioc
+project on
+ http://alioth.debian.org/projects/pkg-bioc/
+
+Since the packaging was performed in a semi-automated setup, one should
+not expect the Debian packages to match those in quality that are
+accessible via the main Debian distribution. At the same time we
+express our belief that an automated build can closely match the
+installation via methods intrinsic to R in actuality with a considerably
+lower administrative burden particularly for a larger number of machines.
+
+All users are welcomed to join in and aid improving on the packages
+or their documentation.
