+GlusterFS's translator feature is very flexible and there are quite a lot of
+ways one can configure their filesystem to behave like.
+
+Volume Specification is a way in which GlusterFS understands how it has to work,
+based on what is written there.
+
+Going through the following URLs may give you more idea about all these.
+
+* http://www.gluster.org/docs/index.php/GlusterFS
+* http://www.gluster.org/docs/index.php/GlusterFS_Volume_Specification
+* http://www.gluster.org/docs/index.php/GlusterFS_Translators
+
+Mail us any doubts, suggestions on 'gluster-devel(at)nongnu.org'
