+=head1 NAME
+
+deprecate - Perl (core) extension for deprecating the core version of a module,
+	    in favour of the version on CPAN.
+
+
+=head1 SYNOPSIS
+
+    use deprecate;	# always deprecate the module in which this occurs
+
+    use if $[ > 5.010, 'deprecate';	# conditionally deprecate the module
+
+
+=head1 DESCRIPTION
+
+This module is used using C<use deprecate;> (or something that calls
+C<< deprecate->import() >>, for example C<use if COND, deprecate;>).
+
+If the module that includes C<use deprecate> is located in a core library
+directory, a deprecation warning is issued, encouraging the user to use
+the version on CPAN.  If that module is located in a site library, it is
+the CPAN version, and no warning is issued.
+
+=head2 EXPORT
+
+None by default.  The only method is C<import>, called by C<use deprecate;>.
+
+
+=head1 SEE ALSO
+
+First example to C<use deprecate;> was L<Switch>.
