+======================
+
+Warn if a function is a near miss (ie. the name is very similar and the function signiture is the same) to a virtual function from a base class.
+
+Example:
+
+.. code-block:: c++
+
+  struct Base {
+    virtual void func();
+  };
+
+  struct Derived : Base {
+    virtual funk();
+    // warning: Do you want to override 'func'?
+  };
