9 * Versions of malloc and friends that check their results, and never return
10 * failure (they call fatal if they encounter an error).

14 * software must be clearly marked as such, and if the derived work is
15 * incompatible with the protocol description in the RFC file, it must be
16 * called by a name other than "ssh" or "Secure Shell".
