RE: [cobalt-users] script to check for updates at Cobalt

["Loryan Strant" <cobalt-users@xxxxxxxxxx>]

Heya,

Why not add functionality to it so that it downloads the latest update into
a directory on the Cobalt, and notifies you of that? If I could code, I add
it myself, but I'm stupid. :-)

Subject: [cobalt-users] script to check for updates at Cobalt


I guess everybody, like myself, want's to stay on top of available packages
from Cobalt. So I've written a script that checks the webpage and will mail
you when something has changed.
Cron it every day as root and you have one thing less to check everyday.
(do not forget to change the email address to something suitable)
