tclap looks really nice. I've written a small test to see if our
current cmd line options could replaced with it. It looks and works
good, but I've used UnlabeledMultiArg to add the option of adding some
songs that should be loaded at start. Unfortunately because of this
tcalp won't throw an exception if I misspelled an option while using
UnlabeledMultiArg. This misspelled option is then handled as an
argument for UnlabeledMultiArg.
Is there a way to have UnlabeledMultiArg and still get an error if
I use "--resourcepath" instead of "--resourcePath"?
best,
Max
