+% version 0.5
+% date: 2009_02_20
+%
+% History of 0.5 version
+% 1 - single row key definition without a fltpoint registry
+% 2 - add a package warning if the keys generate an override
+% 3 - new feature: id key for \add command
+% 4 - Fixed bug in single row key definition
+% 5 - add warning or error internal command, at the end of the listing code
+% 6 - new feature: interval keys 'from' and 'until' in opt arg of the \perc and \add command
