* This file performs some of the things login(1) normally does. We cannot
* easily use something like login -p -h host -f user, because there are
* several different logins around, and it is hard to determined what kind of
* login the current system has. Also, we want to be able to execute commands
* on a tty.
* As far as I am concerned, the code I have written for this software

* incompatible with the protocol description in the RFC file, it must be
* called by a name other than "ssh" or "Secure Shell".
