[2410]	5	! This module controles the interface towards the model ORCHIDEE.
[781]	6	!
[2410]	7	! Compatibility with ORCHIDIEE :
[2571]	8	! This module is compiled only if CPP key ORCHIDEE_NOZ0H is defined.
	9	! This version can be used with ORCHIDEE/trunk revision 2961-3525.
	10	! It is possible to use this interface with later versions of ORCHIDEE/trunk than 3525 but
	11	! in that case the option ROUGH_DYN=y in ORCHIDEE should not be set.
[2410]	12	! This interface can also be used with ORCHIDEE/trunk revision 1078-2960 if changing
	13	! coszang=yrmu0 into sinang=yrmu0 at 2 places later below in this module.
