%description
R-level and C++-level functionality to generate random deviates from and
calculate moments of a Truncated Normal distribution using the algorithm
of Robert (1995) <DOI:10.1007/BF00143942>. In addition to RNG, functions
for calculating moments, densities, and entropies are provided at both
levels.
