Mars GCM:

• Make a single README file (get rid of REAME.exec) and update "compile" script to (hopefully) better illustrate how to compile utilities
• Update utilities zrecast and lslin: zrecast.F90: Force the vertical interpolation of any variable starting by "rho" to be in log space (as it should for density, molecular concentration in mol.cm-3 etc..). Set missing value to 1.E20 lslin.F90: fix various problems in the output.

+## BUT first you must customize this script to your personal settings:
+# 1) set up the correct environment; e.g. environment variable
+#    NETCDF_HOME should point to your NetCDF distribution root directory
+#    (and possibly you might need to "module load ..." a few things)
+# 2) put the appropriate compiler and compiler options
+#    in variables COMPILER and COMPILER_OPTIONS
+# 3) Note that when you will run the executable, you might need to
+#    also add the paths to the used libraries (e.g. $NETCDF_HOME/lib)
+#    in environment variable LD_LIBRARY_PATH (most often the "module load ..."
+#    command does this, so you should run it before running the executable)

-#-L/distrib/local/netcdf/pgi_7.1-6_32/lib -lnetcdf  -o $1.e
+# Setup: (see at the end of this script for real world examples)
+# possibly source some modules here and adapt variables below:
+NETCDF_HOME="/path/to/the/NetCDF/root/directory"
+COMPILER="gfortran"
+COMPILER_OPTIONS="-O2"

-#pgf90 $1.F90 \
-ifort $1.F90 \
--I$NETCDF/include \
--L$NETCDF/lib -lnetcdf -o $1.e
+# Compilation:
+# (on some very old systems the Fortran NetCDF library is included
+#  in the C library and "-lnetcdff" should be replaced with "-lnetcdf")
 
-# Before running that on you computer you might want to change :
-# 1) replace "pgf90" with the name of your favorite compiler 
-#    (you may also add some non-agressive optimization options e.g. -O2)
-# 2) replace "/distrib/local/netcdf/pgi_7.1-6_32/lib" with the
-# address of the
-# directory that contains the NetCDF library (file libnetcdf.a that can
-# be obtained for free on
-# http://www.unidata.ucar.edu/packages/netcdf/index.html
-# (see user manual)
+$COMPILER $COMPILER_OPTIONS $1.F90 \
+-I$NETCDF_HOME/include \
+-L$NETCDF_HOME/lib -lnetcdff \
+-o $1.e
+
 #
-# 3) Replace "/distrib/local/netcdf/pgi_7.1-6_32/lib" with the address of the
-# directory that contains the NetCDF  include file "netcdf.inc"
-# that can be obtained at the web address above.
-# 
-# 4) The "-Bstatic" option is here to ensure that the executable will
-# work on any Linux machine (only necessary if you want to export the
-# executable from a machine to another).
+# Example of a setup on a simple Linux system where the netcdf library
+# is in a personal location /home/myacount/netcdf directory:
+# NETCDF_HOME=/home/myaccount/netcdf
+# COMPILER="gfortran"
+# COMPILER_OPTIONS="-O2"
+# And of course the LD_LIBRARY_PATH environement variable should contain
+# path "/home/myaccount/netcdf/lib" to be able to run the executable
+#
+# Example of a setup on LMD CentOS7 machines using gfortran and NetCDF 4.5:
+# module purge
+# module load gnu/7.2.0
+# module load netcdf4/4.5.0-gfortran72
+# NETCDF_HOME=/opt/netcdf45/gfortran72
+# COMPILER="gfortran"
+# COMPILER_OPTIONS="-O2"
+# And of course modules above need be loaded before running the executable
+#
+# Example of a setup on the Ciclad cluster using ifort and NetCDF 4.3
+# module purge
+# module load intel/15.0.6.233
+# module load netcdf4/4.3.3.1-ifort
+# NETCDF_HOME=/opt/netcdf43/ifort
+# COMPILER="ifort"
+# COMPILER_OPTIONS="-O2 -ip"
+# And of course modules above need be loaded before running the executable
