Really this is an extension to Marcin's answer.
But you could also try passing "rubbish" arguments to see if you get any errors back. Getting any response from the executable directly in the shell will mean that it is likely looking at the arguments you're passing, with an error response being close to a guarantee that it is.
Failing that you might have to directly ask the publishers/creators/owners... sniffing the binaries yourself just seems like far too much work for an end-user.
