update-motd 3.1-0ubuntu1 (amd64 binary) in ubuntu karmic

 .
 This package installs a script in /etc/profile.d that dynamically generates
 a message-of-the-day by running scripts installed in /etc/update-motd.d,
 in lexical order.
 .
 Other packages, or system administrators should symlink scripts into
 /etc/update-motd.d, pre-pending a 2-digit number to handle ordering.
