No one of them. AFAIK, at this moment, recent and the most clear code is
located at /share/contrib/vector3d.

It was discussed on this list. It's better to revise vector calculus-related
code first and merge different implementations. (I plan to work on it.)

/share/contrib/vector3d works nice.
Cartesian, cylindrical and spherical coordinates should be pre-defined in both
packages.
