We've got some french doors and I'd like to seal them as well as possible. There is a gap where I can see light in the middle. The left door has a sliding lock/post that goes down into the ground. The door bottom has been cut to accommodate this, reducing the effectiveness of the left door seal.
Any suggestions for getting this sealed up to keep pests out?
I'm considering a screen door as a last resort - this solution would have benefits of letting us open the doors when weather is nice, keeping the cat in and the bugs out.
Thanks for your advice.

I didn't do anything very fancy, I just kept the sweep to the full length of the door and cut a whole for the bottom bolt to go through. I then left the operable door's sweep a little long to make sure there was contact between both sweeps. It's cut down on the scorpions.
