Change 100699 by dongmei at soc-dongmei-sebsd on 2006/07/06 07:42:48

	Modified to support making modular policy,if want to make modular policYnot monolithic policy, should to modify the MONOLITHIC to n in build.conf,then run: gmake policy. That will create loadable modular policy. Then based on this you can write your own loadable modular policy as follows:
	write myapp.te file#include the private types for module and allow rules
	write myapp.fc file#define the files' security context
	write myapp.if file#define the interface for other modules
	make install-header #to install the policy header file to /usr/share/sebsd/include/
	make -f /usr/share/sebsd/include/Makefile #create the myapp.pp module
	semodule -i myapp.pp # load the myapp.pp policy module
	semodule -l # using this command can lookup the myapp.pp policy module's status
