Smoke editing?

[whammy 0]

Can someone pls tell me what the parameters are in the following code for smoke definition? I'm wanting to make a tall, dense long lasting column of smoke to use with wrecked vehicles.

class Smoke

{

interval=0.010000;

cloudletDuration=4.000000;

cloudletAnimPeriod=1.000000;

cloudletSize=0.250000;

cloudletAlpha=1.000000;

cloudletGrowUp=1.500000;

cloudletFadeIn=0.000000;

cloudletFadeOut=5.000000;

cloudletAccY=-0.300000;

cloudletMinYSpeed=0;

cloudletMaxYSpeed=10;

cloudletShape="cl_basic";

cloudletColor[]={1,1,1,0};

initT=1000;

deltaT=-500;

class Table

{

class T1

{

maxT=0;

color[]={0.700000,0.700000,0.700000,1};

};

class T2

{

maxT=1000;

color[]={0.400000,0.400000,0.400000,1};

};

};

density=1.000000;

size=1.500000;

initYSpeed=1.000000;

timeToLive=1.00000002004087728E20;

in=3.000000;

out=0.000000;

};
