The following attributes specify position:
pos=<vecspec>
Specifies an absolute position
offset=<vecspec>
Specifies an relative position to the target or destination
vecspec: x,y,z | randvec(radius)
radius: number[au]
As shown above, the vector can be specified as either a tuple seperated by commas, or as the special randvec() function which generates a random vector with the specified radius. The radius can be given either in meters or in astronomical units (AU)
As a special feature, the "pos" attribute can specify "warp" when a target object has been given. This will then compute the destination position at the target as if the user had "warped" there. This effectively simulates a warp. <\p>
