Yes, that would be a good tool :-)

anxenc does a similar thing, but poorly -- it rebuilds the file from
its packets, and usually ends up quite a bit bigger; it also adds a
CMML track.

"hogg addskel" does what we want, you can get hogg from
http://www.kfish.org/software/hogg
However, it's a lot slower than an oggz version would be (due to my
poor Haskell optimization skills, not due to the choice of language
;-)

sorry that I haven't made a point of keeping the functionality of
oggz-tools and hogg in sync :-/

Apropos this; I was wondering about mime-types to be used in
Skeleton.  audio/vorbis for instance is not a current recommendation
for general use to avoid irritation to the IETF (as I understand) and
currently, for example, audio/x-ogg is suggested.  What is the opinion
on using the final codec mime types (audio/vorbis for instance) in
Skeleton, as this information is static and as it doesn't overlap with
anything anyone else is doing?
