	51	!! Introduction : \|
	52	!! -------------- \|
	53	!! Every ice-covered grid cell is characterized by a series of state \|
	54	!! variables. To account for unresolved spatial variability in ice \|
	55	!! thickness, the ice cover in divided in ice thickness categories. \|
	56	!! \|
	57	!! Sea ice state variables depend on the ice thickness category \|
	58	!! \|
	59	!! Those variables are divided into two groups \|
	60	!! * Extensive (or global) variables. \|
	61	!! These are the variables that are transported by all means \|
	62	!! * Intensive (or equivalent) variables. \|
	63	!! These are the variables that are either physically more \|
	64	!! meaningful and/or used in ice thermodynamics \|
	65	!! \|
	66	!! Routines in limvar.F90 perform conversions \|
	67	!! - lim_var_glo2eqv : from global to equivalent variables \|
	68	!! - lim_var_eqv2glo : from equivalent to global variables \|
	69	!! \|
	70	!! For various purposes, the sea ice state variables have sometimes \|
	71	!! to be aggregated over all ice thickness categories. This operation \|
	72	!! is done in : \|
	73	!! - lim_var_agg \|
	74	!! \|
	75	!! in icestp.F90, the routines that compute the changes in the ice \|
	76	!! state variables are called \|
	77	!! - lim_dyn : ice dynamics \|
	78	!! - lim_trp : ice transport \|
	79	!! - lim_itd_me : mechanical redistribution (ridging and rafting) \|
	80	!! - lim_thd : ice halo-thermodynamics \|
	81	!! - lim_itd_th : thermodynamic changes in ice thickness distribution \|
	82	!! and creation of new ice \|
	83	!! \|
	84	!! See the associated routines for more information \|
