+ *
+ * This header contains an \c empty_deleter implementation. This is an empty
+ * function object that receives a pointer and does nothing with it.
+ * Such empty deletion strategy may be convenient, for example, when
+ * constructing <tt>shared_ptr</tt>s that point to some object that should not be
+ * deleted (i.e. a variable on the stack or some global singleton, like <tt>std::cout</tt>).
