It is a tool I created myself for figuring out the contents of layered docker images.

It does these things:

1. Compares two docker images to see exact file differences

2. Diffs the contents of two directory structures

3. Views contents of a docker image without mounting it or using docker itself

4. Generates a standalone index of the contents of a docker image

5. Determines the resultant layer composition of a directory within a docker image

6. Extracts a specific pathed file from a layered docker image

It is extremely helpful when trying to determine the exact differences between two different builds of the same Dockerfile.
