You sent this to the Yocto list so I'll give you the Yocto reply. I see
the position being something like:

Poky = Bitbake + OE-Core + meta-yocto + included docs

Yocto = Several separate software projects (Poky, Pseudo, Swabber,
Matchbox, Kernel tools, other layers)

We have Scott's new overall Yocto developers guide and the you end up
diving into various pieces, each of which have deeper more technical
references. So we are trying to ensure the Yocto documentation is
consistent and up to date and take people from a high level down to the
appropriate technical details.

There are some older references around which we really need to remove or
update. The berlios bitbake manual page really needs to be removed as
its out of date and we need to figure out putting an up to date one
somewhere (and preferably automate updating it from the repo). The Poky
website really needs to be rewritten and those older manuals removed and
replaced with links to the Yocto pieces. The OE-Core wiki is probably
ok.

Does that help?
