tbz file from pkg

[Lonnie Cumberland]

Thanks All,

Since  the pkg command returns txz (tar+xz) compressed files during a
fetch, I am going to try to come up with a shell script that will loop
through all of the txz files in a folder and convert each one to a tbz
(tar+bzip2) compressed file.

I think that might be helpful to others as well.
Cheers
