+but it contains no R code or function documentation.  There is a shared object
+containing part of the @code{CVODES} library, but it is not accessible from R.
+@code{r-stanheaders} is only useful for developers who want to utilize the
+@code{LinkingTo} directive of their package's DESCRIPTION file to build on the
+Stan library without incurring unnecessary dependencies.  The Stan project
+develops a probabilistic programming language that implements full or
+approximate Bayesian statistical inference via Markov Chain Monte Carlo or
+variational methods and implements (optionally penalized) maximum likelihood
+estimation via optimization.  The Stan library includes an advanced automatic
+differentiation scheme, templated statistical and linear algebra functions that
+can handle the automatically differentiable scalar types (and doubles, ints,
+etc.), and a parser for the Stan language.  The @code{r-rstan} package provides
+user-facing R functions to parse, compile, test, estimate, and analyze Stan
+models.")
