# C<Bivio::Auth::Permission> is used to specify a task's access
# permissions.  See L<Bivio::Agent::Task|Bivio::Agent::Task> for
# how the permissions are used.
#
# See L<Bivio::Agent::TaskId|Bivio::Agent::TaskId> and
# L<Bivio::Delegate::TaskId|Bivio::Delegate::TaskId>
# for how you define permissions on tasks.
#
# See L<Bivio::Agent::Task|Bivio::Agent::Task> and
# L<Bivio::Delegate::SimpleAuthSupport|Bivio::Delegate::SimpleAuthSupport>
# for how permissions are checked.
#
# See L<Bivio::Biz::Model::RealmRole|Bivio::Biz::Model::RealmRole>
# and L<Bivio::Agent::Request|Bivio::Agent::Request> for how users
# are assigned roles in realms.  This table must be configured if
# you want to use permissions.
#
# You can avoid the use of permissions by delegating
# L<Bivio::Auth::Support|Bivio::Auth::Support> to
# L<Bivio::Delegate::NoDbAuthSupport|Bivio::Delegate::NoDbAuthSupport>.
