どこに？
どこにshared_ptrの利用は手動メモリ管理の範囲内ですってはっきり書かれてるの？
shared_ptrに言及してるのはそのページでは↓ここしかないけど？
「This can also be used with deterministic reference counting. In C++, this ability is put to further use to automate memory deallocation within an otherwise-manual framework, use of the shared_ptr template in the language's standard library to perform memory management is a common paradigm. shared_ptr is not suitable for all object usage patterns, however. 」
