+sudosh is a filter and can be used as a login shell. sudosh takes advantage
+of pty devices in order to sit between the user's keyboard and a program, in
+this case a shell.
+
+sudosh was designed specifically to be used in conjunction with sudo or by
+itself as a login shell.. sudosh allows the execution of a root shell with
+logging. Every command the user types within the root shell is logged as
+well as the output.
+
+How is this different than "sudo -s" or "sudo /bin/sh" ?
+
+Using "sudo -s" or other methods doesn't log commands typed to syslog.
+Generally the commands are logged to a file such as .sh_history and if you
+use a shell such as csh that doesn't support command-line logging you're
+out of luck.
+
+sudosh fills this gap. No matter what shell you use, all of the command
+lines are logged to syslog (including vi keystrokes.)
+
+See README in /usr/doc/sudosh2-<version> for configuration and usage.
