Preventing pungi from including all langpacks?

... how do I compose an image (for Fedora 20) that does not include 
every language pack? A very simple kickstart script that only includes 
'@core' in the '%packages' section will now pull in every langpack for 
hunspell, for example. I am trying to reduce the size of the resulting 
image.

Thanks,
