Hey Alex,
Glad you like it so far :)
Currently the only way to handle multiple dlls is to pass them one-by-one as arguments like you have done.
Admittedly I've focussed more on the architecture than anything and as such the console app isn't as user friendly as it should be. I believe if you call it without any params it'll show you the syntax, but there's little more to it than what you already know.
Thanks,
James
