+    (description
+     "This package provides optimized functions and flexible combinatorial
+iterators implemented in C++ for solving problems in combinatorics and
+computational mathematics.  It utilizes the @code{RMatrix} class from
+@code{RcppParallel} for thread safety.  There are combination/permutation
+functions with constraint parameters that allow for generation of all results
+of a vector meeting specific criteria.  It is capable of generating specific
+combinations/permutations which sets up nicely for parallelization as well as
+random sampling.  Gmp support permits exploration where the total number of
+results is large.  Additionally, there are several high performance number
+theoretic functions that are useful for problems common in computational
+mathematics.")
