"Gnome-schedule is a graphical user interface to 'crontab' and
'at', both used to schedule tasks. It supports periodical tasks and
tasks that happens once in the future. It is written in python
using pygtk.
"Gnome-schedule also supports titles and icons for your tasks so
that they are more easily to keep track of. And you can create
templates so that you won't have to create the same task again and
again. So that if you want to schedule a virus check at 03:00
today, you can save it as a template and choose it from an dropdown
box when you want. Or want to compile the kernel... again... at
00:00. This is saved in gconf and may easily be shipped with each
distribution..."
