 .. method:: socket.recv_into(buffer[, nbytes[, flags]])
 
    Receive up to *nbytes* bytes from the socket, storing the data into a buffer
-   rather than creating a new string.     If *nbytes* is not specified (or 0),
-   receive up to the size available in the given buffer. See the Unix manual page
-   :manpage:`recv(2)` for the meaning of the optional argument *flags*; it defaults
-   to zero.
