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