39	c subject:
40	c --------
41	c PROGRAM useful to run physical part of the martian GCM in a 1D column
42	c
43	c Can be compiled with a command like (e.g. for 25 layers)
44	c "makegcm -p mars -d 25 testphys1d"
45	c It requires the files "testphys1d.def" "callphys.def"
46	c and a 'run.def' file (containing a "INCLUDEDEF=callphys.def" line)
47	c and a file describing the sigma layers (e.g. "z2sig.def")
