string texture = ""; // Texture used for particles. Texture must be in prim's inventory.
// SECTION TWO: FLOW -- These settings affect how Many, how Quickly, and for how Long particles are created.
// Note,
integer count = 10; // Number of particles created per burst, 1
to 4096
float rate = 0.5; // Delay between bursts of new particles, 0.0 to 60, 0.1
float age = 20.0; // How long each particle lives, 0.1 to 60, 10.0
float life = 0.0; // When to stop creating new particles. never stops if 0.0
// SECTION THREE: PLACEMENT -- Where are new particles created, and what direction are they facing?

float innerAngle = PI_BY_TWO; // "spread", for all ANGLE patterns, 0(default) to PI

// PSYS_SRC_PATTERN_EXPLODE (sends particles in all directions)
// PSYS_SRC_PATTERN_DROP (ignores minSpeed and maxSpeed. Don't bother with count>1 )
// PSYS_SRC_PATTERN_ANGLE_CONE (set innerangle/outerange to make rings/cones of particles)
// PSYS_SRC_PATTERN_ANGLE (set innerangle/outerangle to make flat fanshapes of particles)
vector omega = <0,0,0>; // How much to rotate the emitter around the <X,Y,Z> axises. <0,0,0>
*)
// Warning, there's no way to RESET the emitter direction once you use Omega!!
// You must attach the script to a new prim to clear the effect of omega.
// SECTION FOUR: MOVEMENT -- How do the particles move once they're created?
integer followSource = FALSE; // TRUE or FALSE
, Particles move as the emitter moves, (TRUE disables radius!)
integer followVel = TRUE; // TRUE or FALSE
, Particles rotate towards their direction
integer wind = FALSE; // TRUE or FALSE
, Particles get blown away by wind in the sim
integer bounce = FALSE; // TRUE or FALSE
, Make particles bounce on Z altitude of emitter

// SECTION FIVE: Ama's "Create Short Particle Settings List"
integer enableoutput = FALSE; // If this is TRUE, clicking on your emitter prim will cause it to speak
// very terse "shorthand" version of your particle settings. You can cut'n'paste
// this abbreviated version into a call to llParticleSystem([ ]); in another script.
// Pros: Takes up far less scripting space, letting you focus on the rest of your code.
// Cons: makes tune your settings afterwards rather awkward

// Script variables
