-molly-guard
-===========
-
-molly-guard attempts to prevent you from accidentally shutting down or
-rebooting remote machines. It does this by injecting a couple of checks before
-the existing commands: halt, reboot, shutdown, and poweroff.
-
-It does this by putting scripts with the same names into /usr/sbin, so it only
-works if you have /usr/sbin before /sbin in your $PATH!
-
-The checks are:
-
-  - test whether the current pty has been created by sshd
-  - test whether a variable $SSH_CONNECTION exists
-
-If any of these tests are successful, molly-guard asks you to type the
-machine's hostname, which should be sufficient to prevent you from doing
-something by accident.
-
-The following situations are still UNGUARDED. If you can think of ways to
-protect against those, please let me know!
-
-  - running sudo within screen or screen within sudo; sudo eats the
-    $SSH_CONNECTION variable, and screen creates a new pty.
-
-  - executing those command in a remote terminal window, that is a XTerm
-    started on a remote machine but displaying on the local X server.
-
-You have been warned. You can use the --molly-guard-do-nothing switch to
-prevent anything from happening, e.g.
-
-  halt --molly-guard-do-nothing
