41	! Purpose
42	! -------
43	! Run the physics package of the universal model in a 1D column.
44	!
45	! It can be compiled with a command like (e.g. for 25 layers):
46	! "makegcm -p std -d 25 rcm1d"
47	! It requires the files "callphys.def", "z2sig.def",
48	! "traceur.def", and "run.def" with a line "INCLUDEDEF=callphys.def"
49	!
