I'm trying to construct a command line that has an
optional switch and an optional unlabled arg.
When I enter debug -l, an exeception gets throw saying
that I don't have one of the required args.
around line 235 unlabeledvaluearg.h you have.
: ValueArg<T>("", name, desc, true, val, typeDesc, v)
I think hardwireing req to true is the problem. I changed
my code to this and this particular problem went away.
I didn't dig enough to figure out if this broke other stuff,
but basically I should be able to state where or not this
: ValueArg<T>("", name, desc, ignoreable, val,
