[boost] [ptr_container]ptr_multimap difference in doc and code

Hi, I have found some differences in documentation for ptr_multimap, and its real implementation. In code: template< class U > iterator insert( key_type& key, std::auto_ptr<U> x ) { return insert( key, x.release() ); } In documentation: template< class U > iterator insert( const key_type&, std::auto_ptr<U> x ); The difference is in first argument of this function. I don't known which way is right to submit the bug report. Could somebody please help me? Best Regards, Sergei
