Spline path import

Hello I want to import a file in unity which has spline paths from (3ds max) same file also works in maya and now I want it in my game,I have a script which is amazing for creating the paths in unity Here is a link:

download and from the menu->GameObject->createOther->bezierCurve
Or just add it to a null gamobject.
It can have points and each point has two handles that can set the tangent and things like that.

But how do I get this info from the paths in maya?Is there any other way?

Sorry looks like the link was missing for some reason updated.
