Hi Cecelia,

I understand your concerns. Jeff is is on vacation so this will have to 
wait until he comes back. It think it will be his decision as to whether 
gridspec goes into cf 1.7 directly, or whether a separate web page 
should be written in the mean time. I'd be happy to add a gridspec 
version (cf_gridspec_version = 1.0.0) or some other tags but I'd rather 
do this in consultation with Jeff.
