The manual includes a section titled "Serialization Implementations Included in the Library"
which touches upon this. The code that implements it can be found in
header file oserializer.hpp:

struct save_array_type
    static void invoke(Archive &ar, const T &t){
        // consider alignment
        int count = sizeof(t) / (
            static_cast<const char *>(static_cast<const void *>(&t[1]))
            - static_cast<const char *>(static_cast<const void *>(&t[0]))
        ar << BOOST_SERIALIZATION_NVP(count);
        int i;
        for(i = 0; i < count; ++i)
            ar << make_nvp("item", t[i]);

loading array code is found in iserializer.hpp
