Arg. Too early this morning. That should have been something like:

>  BBLAYERS = " \
>>  	http://url.to.my.tarball/tarball.tar.gz;localLayer=/path/to/layer \
>>  	git://gitserver.com/git/repo;proto=http;localLayer=/path/to/layer/two \
>>         /path/to/layer/three \
>>         /path/to/layer/four \
>

or something to that effect.
