+     "This @code{r-rbenchmark} package is inspired by the Perl module Benchmark,
+and is intended to facilitate benchmarking of arbitrary R code.  The library
+consists of just one function, benchmark, which is a simple wrapper around
+system.time.  Given a specification of the benchmarking process (counts of
+replications, evaluation environment) and an arbitrary number of expressions,
+benchmark evaluates each of the expressions in the specified environment,
+replicating the evaluation as many times as specified, and returning the results
+conveniently wrapped into a data frame.")
