   "Bind each custom variable FORM to the value of its VAL.
 
 FORMS is a list of pairs of values [FORM VAL].
+`customize-set-variable' is called sequentially on each pairs
+contained in FORMS. This means `csetq' has a similar behaviour as
+`setq': each VAL expression are evaluated sequentially, i.e. the
+first VAL is evaluated before the second, and so on. This means
+the value of the first FORM can be used to set the second FORM.
 
-If FORM has a custom setter, use it to set FORM to VAL.
-Otherwise, use `set-default'.
+The return value of `csetq' is the value of the last VAL.
