+Run ssh commands on multiple hosts (sequentially), but also be able to take a
+password and forward it on to each of the hosts.  This is useful when SSH keys
+are not set up on the hosts.  The hosts that you log into are read from the
+`hosts` environment variable.  Examples of invocation:
+
+  hosts='farm2 farm3 farm4' mssh -l root 'usermod -a -G admin yang'
+  hosts='farm2 farm3 farm4' mssh -l root 'echo ... >> .ssh/authorized_keys'
+
+This is also a nice, simple demo of how tty/pty stuff works.
