+ * @class ACE_Managed_Object
+ *
+ * @brief Wrapper for interface to allocate an object managed by the
+ * ACE_Object_Manager.
+ *
+ * This template class wraps an interface that is used to
+ * allocate and access an object that is managed by the
+ * ACE_Object_Manager.  Because static template member functions
+ * are not supported by some compilers, it is a separate
+ * (template) class.
+ * This interface is typically used to replace a static object
+ * with one that is dynamically allocated.  It helps to avoid
+ * problems with order of static object
+ * construction/destruction.  Managed objects won't be allocated
+ * until needed, but should be allocated when first needed.  And
+ * they are destroyed in the reverse order of construction.
+ * <get_preallocated_object> accesses a "preallocated" object,
+ * i.e., one that is identified by a value in the
+ * ACE_Object_Manager:: Preallocated_Object enum.  These objects
+ * are used internally by the ACE library.
+ * Hooks are provided for the application to preallocate objects
+ * via the same mechanism.
+ * ACE_APPLICATION_PREALLOCATED_OBJECT_DECLARATIONS can be used
+ * to define enum values;
+ * ACE_APPLICATION_PREALLOCATED_OBJECT_DEFINITIONS can be used
+ * to define the corresponding objects.  The format of the ACE
+ * internal library definitions should be followed.  And
+ * similarly, ACE_APPLICATION_PREALLOCATED_ARRAY_DECLARATIONS
+ * and ACE_APPLICATION_PREALLOCATED_ARRAY_DEFINITIONS can be
+ * used to preallocate arrays.
+ * By default, preallocation uses dynamic allocation.  The
+ * preallocated objects and arrays are allocated off the heap in
+ * the ACE_Object_Manager constructor.  To statically place the
+ * preallocated objects in program global data instead of on the
+ * heap, #define ACE_HAS_STATIC_PREALLOCATION prior to building
+ * the ACE library.
