# We control what versions of what we download based on the KEYWORDS we
# are using for the various arches. Thus if we want grsec1 stable we run
# the with "arch" ACCEPT_KEYWORDS or ~arch and we will get the
# grsec-2.0-preX which has alot more features.

# the only thing that should ever differ in one of these 1.9.x ebuilds
# and 2.x of the same kernel version is the KEYWORDS and header. 
# shame cvs symlinks don't exist
