+ * 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.
