#
# Makefile for the security policy.
#
# Targets:
#
# install - compile and install the policy configuration, and context files.
# load - compile, install, and load the policy configuration.
# reload - compile, install, and load/reload the policy configuration.
# relabel - relabel filesystems based on the file contexts configuration.
# checklabels - check filesystems against the file context configuration
# restorelabels - check filesystems against the file context configuration
# and restore the label of files with incorrect labels
# policy - compile the policy configuration locally for testing/development.
#
# The default target is 'policy'.
#
#
# Please see build.conf for policy build options.
