+	bool "host checksec"
+	help
+	  This tool provides a shell script to check the
+	  properties of executables
+	  (PIE,RELRO,Stack Canaries,Fortify Source).
+	  It also has a kernel test mode that can run on target
+	  for testing of PaX, ASLR, heap and config hardening.
+
+	  NOTE: when using this tool as a host tool, the tool
+	  can offline check a target folder of elf files for
+	  hardening features enabled in those elf files.  There
+	  are other features of this tool, like the kernel test
+	  feature that are not functional offline, but require the
+	  user to execute in a chroot or on target.
