#  Welcome, this is the modern traceur.def !
# 
#         ---> DON'T TOUCH/REMOVE THE FIRST LINE OF HEADER #ModernTrac-v1 <---
#
# * You can use this area to write as many comments as you want starting lines with #.
# * You cannot have comment lines in the middle nor at the end, only at the top.
#
#
# 0. Philosophy  This modern version of traceur.def gather in a single file what was
# ~~~~~~~~~~~~~  previously in traceur.def AND gases.def plus some hard-coded things.
#
# 1. Structure  After the header, first line is the total number of modern tracers in
# ~~~~~~~~~~~~  your file, ie not only tracers sent to dynamics, but also species that
#               takes part in the composition, radiative transfer, chemistry, etc.
#
#               Then, each line needs to start with the specie name ... and that's the
#               only mandatory information ! But you can specify all the options you
#               want in separate blocks following 'option=value', assuming this option
#               is defined in traceur_h.F90 & initracer.F for physics, infotrac.F90 
#               for dynamics or chimiedata_h.F90 & calchim_asis.F90 for chemistry.
#               Indeed this file is read once by dynamics, once by physics and once by
#               chemistry who keep only the information needed.
#
#               Note that by default a tracer listed below will be sent to dynamics
#               except if you specify is_dyn=0. If nothing is given, then is_dyn=1.
#               Not yet fully implemented.
#
# 3. Options.   Implemented options listed below.
# ~~~~~~~~~~~~  For dynamic see "infotrac.F90".
#               For physic see "initracer.F90".
#               For chemistry see "calchim_asis.F90".
