Thanks for all your comments - I'll submit some patches to the docs when
I get a chance, but see below..

Not sure what you're looking at to see that.  This is what I have:

[trz at empanada dylan-cur]$ pwd

[trz at empanada dylan-cur]$ ls
bitbake        LICENSE   meta-intel     meta-yocto-bsp     README

-rwxrwxr-x. 1 trz trz  4840 Apr 17 11:31 scripts/yocto-layer


No scripts/ in meta-yocto, etc.  So things should work as expected with
sourcing oe-init-build-env, etc.

Right, that's a bug - 'layer' does come from the new yocto-layer command
and shouldn't be there..

See above..
