#
#  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.
