* = 0, 1 or many
now what means ? and + + = 1 or many ? optional ?

• ? : which means that the symbol (or group of symbols in parenthesis) to the left of the operator is optional (it can appear zero or one times) • * : which means that something can be repeated any number of times (and possibly be skipped altogether) • + : which means that something can appear one or more times
doru can you add that to the moose web site? I will add that to the document I'm writing.
