+    """Implementations of functions which have been introduced
+    in R since version 3.0.0. The backports are conditionally
+    exported which results in R resolving the function names to
+    the version shipped with R (if available) and uses the
+    implemented backports as fallback. This way package developers
+    can make use of the new functions without worrying about the
+    minimum required R version."""
