Last change on this file since 5099 was 5099, checked in by abarral, 4 months ago

Replace most uses of CPP_DUST by the corresponding logical defined in lmdz_cppkeys_wrapper.F90
Convert several files from .F to .f90 to allow Dust to compile w/o rrtm/ecrad
Create lmdz_yoerad.f90
(lint) Remove "!" on otherwise empty line
