20000301: .gem files

Glenn,

if you change the eta211 key to eta_grid211, then you will also need to
change the default model key further down in the file (since it is set at
eta211 in the distribution as well). How many grids in your $HDS directory
match that eta_grid211 template? If it is too many, then you might have a 
problem as well.
