5 * This file performs some of the things login(1) normally does. We cannot
6 * easily use something like login -p -h host -f user, because there are
7 * several different logins around, and it is hard to determined what kind of
8 * login the current system has. Also, we want to be able to execute commands
9 * on a tty.

11 * As far as I am concerned, the code I have written for this software
12 * can be used freely for any purpose. Any derived versions of this
13 * software must be clearly marked as such, and if the derived work is
14 * incompatible with the protocol description in the RFC file, it must be
15 * called by a name other than "ssh" or "Secure Shell".
