The GNOME Crontab Editor is a graphical interface to the crontab program. You can use it to create, delete and edit scheduled tasks using a simple point-and-click interface. The GNOME Crontab Editor is written in Perl and uses the Gtk-Perl modules, as well as Locale::Maketext and Gtk::HandyCList.
As of version 0.0.5, the Gnome Crontab Editor supports editing remote crontab files using SSH. To use this feature, you will need to have ssh-agent running, or your public key installed on the remote host.
