+From: Niko Tyni <ntyni@debian.org>
+Subject: Point users to Debian packages of deprecated core modules
+Bug-Debian: http://bugs.debian.org/580034
+
+Class::ISA, Switch, Pod::Plainer, and (partially) Shell were
+deprecated from the Perl core in 5.12.0.
+
+To get a clean transition, perl-modules is going to recommend the separate
+Debian packages of these for one release cycle so that they will be
+pulled in by default on upgrades.
+
+However, on systems configured to ignore recommendations the deprecation
+warnings will still be useful, so modify them slightly to point to the
+separate packages instead.
