# Set: The card "FollowDefaults"
#
# DEPRECATED
#
# Despite its name (*follow defaults)card does not influence defaults for *follow rules.
# What it does is provide a mechanism (with interface) for updating all users so that
# they follow the items that are its content.
#
# PLAN:
module FollowDefaults;
extend Card::Set
def self.source_location; "/Users/ethan/dev/decko/gem/card-mod-follow/set/self/follow_defaults.rb"; end
# - actual defaults should be handled as much as possible with something like
#   the *defaults rule
# - on the *admin page, we can have a link so sharks can update all the pristine cards
#   to use whatever the actual defaults representation is (see previous point)
# - if you truly want to override existing follow rules, that may be monkey territory?
# - we will delete "*follow defaults" after the above are completed
