+##	Tripwire file integrity checker.
+##	</p>
+##	<p>
+##	NOTE: Tripwire creates temp file in its current working directory.
+##	This policy does not allow write access to home directories, so
+##	users will need to either cd to a directory where they have write
+##	permission, or set the TEMPDIRECTORY variable in the tripwire config
+##	file.  The latter is preferable, as then the file_type_auto_trans
+##	rules will kick in and label the files as private to tripwire.
