Package specto: Information

Specto is a desktop application that watches configurable events (such
as website updates, emails, file and folder changes, system processes,
etc) and then trigger notifications.

Specto can watch a website for updates and notify you when there is
activity (otherwise, Specto will just stay out of the way). This changes
the way you work, because you can be informed of events instead of
having to look out for them.
