+
+	<para>
+		The <command>vfs_snapper</command> VFS module exposes snapshots
+		managed by snapper for use by Samba. This provides the ability
+		for remote SMB clients to access shadow-copies via Windows
+		Explorer using the "previous versions" dialog.

+	<title>CONFIGURATION</title>
+
+	<para>
+		The underlying share path must have a corresponding snapper
+		configuration file. The snapshot directory tree must allow
+		access for relavent users.

+	<title>PERMISSIONS</title>
+	<para>
+		Snapper stores snapshots under a .snapshots subdirectory. This
+		directory must permit traversal for any users wishing to access
+		snapshots via the Windows Explorer previous versions dialog.
+		By default, traversal is forbidden for all non-root users.
+		Additionally, users must be granted permission to list snapshots
+		managed by snapper, via snapper's ALLOW_USERS or ALLOW_GROUPS
+		options. Snapper can grant these users and groups .snapshots
+		traversal access automatically via the SYNC_ACL option.
