So here is my first whack at it. One thing to note is there was a DU_DEBUG optional define that defined a -d flag to use for debugging. It seemed like using -d would be more useful for everyone to use for depth then for debug so I modified the slightly oddly thrown in debug stuff to now work with --debug instead. Though when I actually define DU_DEBUG so the #if DU_DEBUG is picked up and used it complains about the function missing so I'm kind of curios if this has worked for awhile.

Anyways any feedback or recommendations would be greatly appreciated so this has a better chance of making its way into the release.

Thank you for your time on this matter!
