[PLUG] Confused about using cacview with mutt and mailcap entries

[Mike Leone <turgon@mike-leone.com>]

So I want to use cacaview, to view jpegs from within mutt, for when I read
email over an ssh tunnel. This is using debian testing. So I installed the
cacautils package, and verified that cacaview works. (JPGs still look like
crap, but I suppose it's better than nothing ...)

Anyway, I'm confused about the mailcap entries. I have this, in /etc/mailcap:

image/jpeg; /usr/bin/cacaview '%s'; test=test -n "$DISPLAY"

but when I try and view an attachment that mutt says  is "image/jpeg", mutt
tells me "No matching mailcap entry found. Viewing as text". So what am I
doing wrong? Mailcap files confuse me. :-)

And if anybody knows of a way to view images (JPGs, specifically) in a
commad-line terminal that even remotely looks like the image, I'm eager to
hear about it.

Thanks
