+                       and some constraints have been introduced.
+                       
+                       1) For the sake of simplicity of the code, perfdata information will only be 
+                        provided when the "description" field is added. 
+                       
+                       2) If the counter you're going to measure is percent-based, the code will detect
+                        the percent sign in its name and will attribute minimum (0%) and maximum (100%) 
+                        values automagically, as well the ¨%" sign to graph units.
+
+                       3) OTOH, if the counter is "absolute", you'll have to provide the following
+                        the counter unit - that is, the dimensions of the counter you're getting. Examples:
+                        pages/s, packets transferred, etc.
+
+                       4) If you want, you may provide the minimum and maximum values to expect. They aren't mandatory,
+                        but once specified they MUST have the same order of magnitude and units of -w and -c; otherwise.
+                        strange things will happen when you make graphs of your data.
