## ATTRIBUTES

### config\_merge\_behavior

This attribute contains the behavior which will config\_merger use to merge particular loaded configurations.

### config\_merger

This attribute contains the instance of Hash::Merge used to merge the *raw\_loaded\_config* into *loaded\_config*.

### loaded\_config
