I love xv - it's my go-to JPEG viewer.  Its command-line interface is
dead simple, and it's lightweight and fast.  It has one problem, though:
it can't display many newer JPEG files.  It comes up with the message:

<filename>: Unsupported JPEG process: SOF type 0xc2

I have to fall back to another viewer (usually ristretto, which I
really don't like) to view these files.  (Working on a file that
xv likes with the Gimp is one good way to make a file it doesn't
like.)

The latest version I've been able to find is 3.10a.  Is there a
newer version out there that can handle all JPEGs?

Hi Charlie,

I agree with you about xv, it's a wonderful piece of software.

The wikipedia has an article on it:
https://en.wikipedia.org/wiki/Xv_(software)

And that article asserts that the 3.10a version (1994-12-29) is the latest,
although there are apparently later patches.

I do think that the license is an important factor here.

If you have luck in your pursuit of a later, better xv, please do post, and
thanks in advance.
