+/** Prevent copy construction and assignment.
+
+    This is used to suppress warnings and prevent unsafe operations on
+    objects which cannot be passed by value. Ideas based on Boost.
+
+    For example, instead of
+
+    @code
+
+    class MyClass
+    {
+    public:
+        //...
+
+    private:
+        MyClass (const MyClass&);
+        MyClass& operator= (const MyClass&);
+    };
+    
+    @endcode
+
+    ..you can just write:
+
+    @code
+
+    class MyClass : public Uncopyable
+    {
+    public:
+        //...
+    };
+    
+    @endcode
+
+    @note The derivation should be public or else child classes which
+          also derive from Uncopyable may not compile.
