+<h3>Cling C++ Interpreter</h3>
+
+<div>
+
+<p><a href="http://cern.ch/cling">Cling</a> is an interactive compiler interface
+   (aka C++ interpreter). It uses LLVM's JIT and clang; it currently supports
+   C++ and C. It has a prompt interface, runs source files, calls into shared
+   libraries, prints the value of expressions, even does runtime lookup of
+   identifiers (dynamic scopes). And it just behaves like one would expect from
+   an interpreter.</p>
