+by r (aka littler) as a lightweight binary wrapper around the GNU R language
+and environment for statistical computing and graphics.  While R can be used
+in batch mode, the r binary adds full support for both shebang-style scripting
+(i.e. using a hash-mark-exclamation-path expression as the first line in
+scripts) as well as command-line use in standard pipelines.  In other words, r
+provides the R language without the environment.")
