 What happens ? namelist_cfg is the parameter file that is where you change values and input files in order to customize your run.
-- change the model time step
-- change the file frequency
+- model time step : rn_rdt is express in seconds
+Default value for ORCA2 is rn_rdt = 5760 sec. 
+How many time steps do the model in 1 day ?  => 1 day is 86400 seconds => 86400/rn_rdt = #time steps per day => for ORCA2 it is 15
+
+- simulation duration : nn_itend is the number of time step
+Default number for ORCA2 is nn_itend = 5840
+How many day last such a simulation ?  nn_itend x rn_rdt / 86400 = 389 that is about a year (?) 
+In the .nc simulation output file "ORCA2_XXXXX_grid_T.nc" one time point is written every 5 days.
+
+- layout and resolution : ln_read_cfg & cn_domcfg
+Default grid specified by reading a configuration file ln_read_cfg = .true. & cn_domcfg = "ORCA_R2_zps_domcfg"
+This configuration use a specific grid ORCA with a 2 degre resolution on average (?) resolution is automatically deduced from the file content. The file must be in HOME/NEMO/cfgs/ORCA2_ICE_PISCES/EXP00.
+
+- wind stress files : sn_wndi & sn_wndj

 What happens ? NEMO's sources (files.F90) are in src and in ./tests/CANAL/MY_SRC here we may want to change them in order to implement new features such as boundary condition shape. In that case we have to compile NEMO each time we change a source file.
