+      Clojure is a dynamic programming language that targets the Java
+      Virtual Machine. It is designed to be a general-purpose language,
+      combining the approachability and interactive development of a
+      scripting language with an efficient and robust infrastructure for
+      multithreaded programming. Clojure is a compiled language - it
+      compiles directly to JVM bytecode, yet remains completely
+      dynamic. Every feature supported by Clojure is supported at
+      runtime. Clojure provides easy access to the Java frameworks, with
+      optional type hints and type inference, to ensure that calls to Java
+      can avoid reflection.
+
+      Clojure is a dialect of Lisp, and shares with Lisp the code-as-data
+      philosophy and a powerful macro system. Clojure is predominantly a
+      functional programming language, and features a rich set of immutable,
+      persistent data structures. When mutable state is needed, Clojure
+      offers a software transactional memory system and reactive Agent
+      system that ensure clean, correct, multithreaded designs.
