+%description
+Functions introduced or changed since R v3.0.0 are re-implemented in this
+package. The backports are conditionally exported in order to let R resolve
+the function name to either the implemented backport, or the respective
+base version, if available. Package developers can make use of new
+functions or arguments by selectively importing specific backports to
+support older installations.
