%description
Fast and efficient sampling from general univariate probability density
functions. Implements a rejection sampling approach designed to take
advantage of modern CPU caches and minimise evaluation of the target
density for most samples. Many standard densities are internally
implemented in 'C' for high performance, with general user defined
densities also supported. A paper describing the methodology will be
released soon.
