+*** R blocks
+    In developing RweaveOrg, Austin created [[file:existing_tools/RweaveOrg/org-sweave.el][org-sweave.el]].  This
+    allows for the kind of blocks shown in [[file:existing_tools/RweaveOrg/testing.Rorg][testing.Rorg]].  These blocks
+    have the advantage of accepting options to the Sweave preprocessor
+    following the #+BEGIN_R declaration.
