(description
"Provides 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.")
