From Jeff's description, it sounded like the package (especially 'package version')
comes from the stuff that is the recipe's *input*, and not the recipe's output
 -- if you've selected to build packages and not just a straight image.

Is 'package' also used in that sense, to describe, say, the tarball for busybox
before it's processed by bitbake and made into an busybox binary ipkg or rpm?

Or am I just muddying the waters further?

BTW, on denzil, I get the following:
$ bitbake -s | grep busybox
busybox                         :1.19.4-r2

Note that this includes the version of busybox (the input source version), as
well as (I think) the recipe revision number.

And yes - a definitive glossary would be great.
