I was looking at the Groovy CliBuilder class, but I noticed that it
appears to use Commons CLI under the covers, so perhaps my question is
better addressed here.
Someone had asked me, for an option where "optionalArg" is true, how do
you tell whether a value was provided? When I do this in Groovy, if I
provide a value, the value of the option gives me the value that was
provided, but if I don't provide a value, Groovy just gives me a boolean
true for the value of the option. I didn't see any method like
"argWasProvided" or anything like that.
