[Genparse-users] Optional arguments

[<li...@mi...>]

Hi Mike,

I think one of the most obvious missing features of Genparse is that
it doesn't yet support optional arguments. getopt_long supports
optional arguments however.

I want to implement it by allowing an optional * both after the
short and the long option. 

Examples:

o* / oparam*	string	"Both short and long option have an optional argument."
p* / pparam	string	"Short option has an optional argument,"
                        "long option requires an argument."
q / qparam*	string	"Short option reqires an argument,"
                        "long option has an optional argument."
