Updated LMDZOR_v6.3 configuration files to follow LMDZOR_v6.2 structure: compilation script instead of makefiles... These chages should be used together with new LMDZ/trunk, IOIPSL/trunk and XIOS/trunk. Only difference between v6.2 and v6.3 is the version of ORCHIDEE: ORCHIDEE_2_2 in v6.2 and ORCHIDEE_3 in v6.3.
