Point Cloud to MAX

How hard would it be to develop a script to load point cloud files (i.e pts files)
into max and be able to render them?(something like cloud2max)
Here's part of a pts file:
Not sure what the first number is (maybe number of points?) and then x y z coordinates and not sure what the 4th column is and then RGB value of the points?
cloud2max stores points in video card memory (what they say in their website).
Thanks.
