Sure, you're welcome. Ask if you need help with the new metalayer.

meta-foo/classes/image_types_bar.bbclass
meta-foo/conf/bblayers.conf.sample
meta-foo/conf/layer.conf
meta-foo/conf/local.conf.sample
meta-foo/conf/machine/bar.conf
meta-foo/conf/site.conf.sample

These are the files you usually need in your new layer.
