# Policies are virtual modules, similar to those defined in the
# "instantate" section of radiusd.conf.
#
# Defining a policy here means that it can be referenced in multiple
# places as a *name*, rather than as a series of conditions to match,
# and actions to take.
#
# Policies are something like subroutines in a normal language, but
# they cannot be called recursively. They MUST be defined in order.
# If policy A calls policy B, then B MUST be defined before A.
