User-agent information page for urlwatch
urlwatch is a tool to watch a
website for changes. When the contents of a website changes, urlwatch
will display a diff (i.e. a file that displays what has changed) on
stdout. If used in conjunction with cron,
these changes can also be mailed to the user who runs urlwatch.
The author of this utility is probably not running urlwatch to monitor
your websites, but a user is.
You can find more information about urlwatch and download it yourself
from this page.
