+#TODO: All gluster and samba paths are assumed for fedora like systems.
+#Some efforts are required to make it work on other distros.
+
+#The preferred way of creating a smb share of a gluster volume has changed.
+#The old method was to create a fuse mount of the volume and share the mount
+#point through samba.
+#
+#New method eliminates the requirement of fuse mount and changes in fstab.
+#glusterfs_vfs plugin for samba makes call to libgfapi to access the volume.
+#
+#This hook script enables user to enable or disable smb share by volume set
+#option. Keys "user.cifs" and "user.smb" both are valid, but user.smb is
+#preferred.
