+Additionally, fast functions for generating random numbers according to a
+uniform, normal and exponential distribution are included.  The latter two use
+the Ziggurat algorithm originally proposed by Marsaglia and Tsang.  These
+functions are exported to R and as a C++ interface and are enabled for use
+with the default 64 bit generator from the PCG family, Xoroshiro128+ and
+Xoshiro256+ as well as the 64 bit version of the 20 rounds Threefry
+engine (Salmon et al., 2011) as provided by the package @code{sitmo}.")
