See my other mail, I have no problem with adding that.

As I said, KChart with our KDChart engine has lived with this situation f=
or=20
almost two years, without problems. The only changes that have been made=20
where one liner get-this-to-compile-on-platform-X changes which are not=20
copyrightable anyway.
If somebody wants to make a substantial contribution to either KDChart or=
=20
KDGantt, we would contact this developer and offer him or her to buy the=20
rights to the change so that we can continue to have identical GPL and=20
commercial versions. I am not too sure that this is going to happen, thou=
gh,=20
as hacking on these is a pretty tough call, both have many hundreds (KDCh=
art=20
even thousands) of design and implementation hours, it's nothing you can =
get=20
into on one weekend...
