I've found some good documentation on building SELinux modules at http://sepolicy-server.sourceforge.net/index.php?page=module-overview. However, this article states, "Note that the syslog.te file must already be preprocessed by m4 if it contains macros." I can't find any clear documentation that describes how to perform this step.
How does one process a policy source file using m4 and what package provides the required macro definitions (i.e.: domain_auto_trans?)
