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. 10 * 11 * As far as I am concerned, the code I have written for this software 12 * can be used freely for any purpose.
