+# Access control file for qemu-bridge-helper
+# https://wiki.qemu.org/Features/HelperNetworking
+#
+# Syntax consists of:
+#   # comment (ignored)
+#   allow all
+#   allow <bridge_name>
+#   deny all
+#   deny <bridge_name>
+#   include /path/to/additional/ACL/file
+#
+# Users are blacklisted by default and 'deny' takes precedence over 'allow'.
+# Including additional ACL files allows file access permissions to be used as
+# a component of the policy to allow access or deny access to specific bridges.
