Last change on this file since 4660 was 4389, checked in by dcugnet, 23 months ago
revert to original "type_trac" management: 4 characters keyword (lmdz, Inca, repr, co2i, into, aeNP, coag no longer a list of component with "\|" separator the parsed (with "\|" separator) version "types_trac" is no longer used the sole routine using a list of component is readTracFiles fix for INCA and CO2Aer modes: setGeneration is now a function, index corrections for had/vadv.
