-// This header defines two shared pointer facilities, lw_shared_ptr<>
-// modeled after std::shared_ptr<>.
-//
-// Unlike std::shared_ptr<>, neither of these implementations are thread
-// safe, and two pointers sharing the same object must not be used in
-// different threads.
-//
-// lw_shared_ptr<> is the more lightweight variant, with a lw_shared_ptr<>
-// occupying just one machine word, and adding just one word to the shared
-// object.  However, it does not support polymorphism.
-//
-// Both variants support shared_from_this() via enable_shared_from_this<>
-// and lw_enable_shared_from_this<>().
