4	! Current revisions:
5	! -----------------
6	! Definition of a colortable to be used for particles.
7	! Output names are changed: surface=groundplate, buildings=topography
8	! Output of messages replaced by message handling routine.
9	! Clipping implemented.
10	! Polygon reduction for building and ground plate isosurface. Reduction level
11	! for buildings can be chosen with parameter cluster_size.
12	! Steering, splitting, and rtsp routines not used on nec.
13	! ToDo: checking of mode_dvrp for legal values is not correct
14	! Implementation of a MPI-1 coupling: __mpi2 adjustments for MPI_COMM_WORLD
