* return is not allowed in main program => stop
* number of variables to be read and written was not computed correctly
* name of the outputfile is now correct
* treat correctly the last variable given with -v option
* correct bugs if LOWMEM is set (variables with length=1, reading of TEXT variables)
* correct types when LFI_INT is 8

Philippe 08/07/2016: it is now possible to compile the bin_tools directly with MESONH using the MNH_TOOLS key.
For the moment, only LFI2CDF is available. The executable are linked to bin_tools/

Philippe 08/07/2016: removed profile_mesonh file (automatically generated from profile_mesonh.ihm at configure)

Philippe 17/06/2016: optimisations: removed unnecessary operations when JSPL=K/ISPLIT, removed unnecessary initialisations

Philippe 17/06/2016: optimisation: change variable status INOUT->OUT, replace update by affectation, removed intermediate variable

J.Escobar:01/06/2016: Bug in retrieve2_nest_infon.f90 :type of ZBUF INTEGER => REAL & use MPI_PRECISION for r4/R8 compatibility

Philippe 14/03/2016: completed .PHONY targets + added .SECONDARY targets and dummy targets (for external Fortran modules)
