+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.")
