Mars GCM: Integration of the detached dust layer parametrizations (rocket dust storm, slope wind lifting, CW, and dust injection scheme, DB). Still experimental, default behaviour (rdstorm=.false., dustinjection=0) identical to previous revision. NB: Updated newstart requires an updated "surface.nc" containing the "hmons" field. EM+MV

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