I have an installation that has been tampered with, and I want to find out what exactly has been changed.

I can run

```
rpm -V MY_PACKAGES
```

which gives me a list of modified files. Now I am looking for a convenient way to see the diffs (assuming that all files have textual content) against the original rpms (which I have available).

What would be the easiest way of doing this, given that I am dealing with ~20 packages and ~200 changed files. Is there something like "rpm diff"???
