+
+deprecate - Perl pragma for deprecating the inclusion of a module in core
+
+=head1 SYNOPSIS
+
+    use deprecate;  # warn about future absence if loaded from core
+
+=head1 DESCRIPTION
+
+This is a PerlOnJava stub. The original pragma warns users when loading
+modules from Perl core that will be removed in future releases.
+
+Since PerlOnJava doesn't have the traditional core/site library directory
+distinction, this pragma is a no-op.
