+AppArmor protects systems from insecure or untrusted processes by running them
+in restricted confinement, while still allowing processes to share files,
+exercise privilege and communicate with other processes. AppArmor is a
+Mandatory Access Control (MAC) mechanism which uses the Linux Security Module
+(LSM) framework.
+
+Note that in order to use AppArmor, you need to have CONFIG_SECURITY_APPARMOR
+setting enabled in the kernel (which is not enabled by default in Slackware).
+So in order to use this, you need to reconfigure & recompile your kernel.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
