%description
Fit Bayesian models in Stan <doi: 10.18637/jss.v076.i01> with
checkpointing, that is, the ability to stop the MCMC sampler at will, and
then pick right back up where the MCMC sampler left off. Custom 'Stan'
models can be fitted, or the popular package 'brms' <doi:
10.18637/jss.v080.i01> can be used to generate the 'Stan' code. This
package is fully compatible with the R packages 'brms', 'posterior',
'cmdstanr', and 'bayesplot'.
