What does what mean? Cross posting? It is a way to post one message to 
multiple groups. I'm not sure of the best way to do it with Outlook...

Well, that doesn't tell where you got it, but I bet Shiro Nakayama knows 
more about how to use it than the people on these groups... ;-)

The word "usage"? It means "how something is used".

The P_Checker() macro makes a pigment, T_Checker() makes an entire 
texture, PatternNumber is any number from 0 to 30.

Something like this:

#include "colors.inc"
#include "checker.inc"

camera {
    orthographic
    location < 0, 0,-1>
    look_at < 0, 0, 0>
    right x*1 up y*1
}

#declare TexA = texture {pigment {color White}}
#declare TexA = texture {pigment {color Black}}

box {<-1,-1, 0>, < 1, 1, 1>
    texture {T_Checker(frame_number, TexA, TexB)}
}

And then render an animation with 30 frames.
