The reason that sort of thing is there is because in the olden days before we had specs or EAPIs or anything like that, eclasses were originally designed and implemented as "classes" in an OO type manner. The idea was that there would be a "base" eclass, and then you'd derive "kde", "gnome" etc eclasses from there, all in a nice hierarchy, and you'd be expected to "override" variables like DESCRIPTION as you go down the tree. As it turns out, eclasses ended up being used in a completely different way. But you still see bits of the original idea cropping up, such as in the words "class" and "inherit" and "base". -- Ciaran McCreesh
