 ## Methods
 
-The *\*_del()* and *\*_compare()* methods are defined based on the methods passed to the *using_\*ptr()* macro. For *csptr* use *csptr_X_share(p)* when sharing ownership of the pointed-to object to others. See example, where x has shared ownership with the shared pointer element in cvec container. Refer to c++ std::shared_ptr for more information.
