scale{

scale the given geometry about the origin

The geometry is scaled about the origin. Either a global factor is given, that scales the geometry identically in all main directions, or three factors are given, representing the stretching in the three main directions (x,y,z):
include{File} ... scale{Factor} ...
or
include{File} ... scale{Factor_x, Factor_y, Factor_z} ...
or one-dimensional strectching
include{File} ... scale{nx, ny, nz, Factor_n} ...
or scaling around a certain point of origin
include{File} ... scale{Ox, Oy, Oz, Factor_x, Factor_y, Factor_z} ...
