-;;; Commentary:
-
-;; Org-Babel support for evaluating Stan [1] source code.
-;;
-;; Evaluating a Stan block can produce two different results.
-;;
-;; 1) Dump the source code contents to a file.
-;;
-;;    This file can then be used as a variable in other blocks, which
-;;    allows interfaces like RStan to use the model.
-;;
-;; 2) Compile the contents to a model file.
-;;
-;;    This provides access to the CmdStan interface.  To use this, set
-;;    `org-babel-stan-cmdstan-directory' and provide a :file argument
-;;    that does not end in ".stan".
-;;
-;; For more information and usage examples, visit
-;; https://orgmode.org/worg/org-contrib/babel/languages/ob-doc-stan.html
