Joft is a script for Autodesk Maya. It helps to convert the soft selection into skin weights, And it has other feature like skinning multiple joints, Create a new joint from soft selection and just create a new joint over the selected vertex.
It makes rigging/skinning a fun thing.
The script creates joints over the previous skin cluster or creates a new one automatically, So it will work with unrigged models as well as fully finished rigs.
