Nurbs curve parameters in Maya?

Question

I get a Maya .ma file, I want to understand the parameters for nurbsCurve, the file has contents like this:

createNode nurbsCurve; # create a nurbsCurve
    setAttr -k off ".v"; # set attribute about knots?
    setAttr ".cc" -type "nurbsCurve"  # attribute setting 
        3 1 0 no 3
        6 0 0 0 1 1 1  
        4  # 4 stand for the below has 4 coordiniates
        7.82436 0.545707 8.54539
        7.86896 0.545707 9.61357
        7.28368 0.53563 9.8433
        6.06638 0.53563 9.89412
        ;
...

I don't understand what the line 3 1 0 no 3 and 6 0 0 0 1 1 1 stands for, anybody understand what these lines stand for?

Here's what I know so far, only the first three figures. [3] [1] [0] corresponds to: [degree] [span] [index of the form: open/closed/periodic]
