Gecko

What is GECKO?

This question needs to be answered by someone familiar with the details of Sugar. It is easy enough to give a general answer, but what we really need to know is what capabilities does GECKO provide to application developers and content developers on the OLPC. Is it just a fancy text widget for GTK+? Or is there something more to it?

GECKO is the Rendering Engine behind Mozilla and Firefox.

There is a Wikipedia entry and a GECKO developers Wiki that may help you get an idea of what GECKO will do.
