+#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 automagically removes shares for volume on every volume stop
+#event by removing the volume related entries(if any) in smb.conf file.
