This is the third document in the series about the development of LUATEX and MKIV. This one goes under the name 'about' as one might wonder what all this development is about. After all we've now reached a state where we can think about future applications instead of improving older features as that process is ongoing.

As we're a bit beyond experimenting now, the focus will be on practical usage and of course we target on applications that the LUA and TEXcombination makes possible, either new or in a renewed form.
