I'm trying to find a way to prevent developers from adding certain file types to the main repo. Is there something like a pre-add hook that could be used?

I found this in another forum but I'm not sure how it was intended to be implemented.

```
git check-attr addtoannex \"$FILE\" | grep -q \": set$\"  
if [ $? -eq 0 ]; then  
    git annex add \"$FILE\"  
else  
    git add \"$FILE\"  
fi  
```
