24	c subject:
25	c --------
26	c PROGRAM useful to run physical part of the venusian GCM in a 1D column
27	c
28	c Can be compiled with a command like (e.g. for 50 layers)
29	c "makelmdz_lmdz -p venus -d 50 rcm1d"
30	c If you want XIOS outputs, then you'll need to compile with MPI and xios:
31	c "makelmdz_lmdz -p venus -parallel mpi -io xios -d 50 rcm1d"
32	c but the model should then be run using a single core, i.e. without mpirun
33
34	c It requires the files "rcm1d.def" "physiq.def"
35	c and a file describing the sigma layers (e.g. "z2sig.def")
36	c
