+    This macro can be used in a class declaration to disable the generation of
+    default copy ctor and assignment operator.
+
+    Some classes don't have a well-defined copying semantics. In this case the
+    standard C++ convention is to not allow copying them. One way of achieving
+    it is to use this macro which simply defines a private copy constructor and
+    assignment operator.
+
+    Beware that simply not defining copy constructor and assignment operator is
+    @em not enough as the compiler would provide its own automatically-generated
+    versions of them -- hence the usefulness of this macro.
+
+    Example of use:
+    @code
+    class FooWidget
+    {
+    public:
+        FooWidget();
+        ...
+
+    private:
+        // widgets can't be copied
+        DECLARE_NO_COPY_CLASS(FooWidget)
+    };
+    @endcode
+
+    Notice that a semicolon should not be used after this macro and that it
+    changes the access specifier to private internally so it is better to use
+    it at the end of the class declaration.
