As the KAlgebra maintainer, I would like to see a deeper explanation on how
KAlgebra would fit in that project, what will the library do? What will be
the library be built upon? I'd suggest libanalitza. That way we could
integrate it into KAlgebra. Maybe we could build kmplot on it at some point
(or just drop kmplot, which is something that I'm not sure we want).

Well anyway, there's a lot to talk about. You know where to reach me. :)
