Done. Here are [two example files](https://github.com/openpreserve/jhove/files/4631306/tiff-with-duplicate-pointer-error.zip) ([source](https://github.com/marhop/literate-binary/tree/master/examples/tiff)) that should raise this error. The first has duplicate pointers in the XResolution and YResolution fields, both referencing the same offset (which would...

If you haven't already settled on something else, I really like [JCommander](http://www.jcommander.org/) for CLI options.

Oops, you're right! I thought JCommander supported clustered options, but I haven't checked in a while (seems it does not). Indeed picocli looks nice, and it even supports autocomplete.

Worth mentioning that there's fmt/159 "EBCDIC-US". However with all the different EBCDIC codepages one PUID alone won't be enough. ~I wonder if PRONOM has (or should have) another concept for...

Yes, exactly. Personally and in theory, I would consider only the formal specification valid, not the examples from the annex. But this is hardly useful in practice because it would...

Your new link works for me, thanks! Let's keep this issue open though until the wiki has been fixed, OK?

Hey, I just updated from 6.5 to 6.7 and the new CLI is such an improvement, you really made my day! Commands like `droid file.jpg` or `droid directory/` now work...
