%description
JAGS (Just Another Gibbs Sampler) is a program for the analysis of
Bayesian statistical models using Markov Chain Monte Carlo (MCMC)
simulation.

JAGS is similar to the BUGS (Bayesian Inference using Gibbs Sampling)
program developed at the MRC Biostatistics Unit, Cambridge, and uses a
dialect of the BUGS language to describe Bayesian hierarchical models.
