+# galera_diff.inc
+# ===============
+#
+# Description
+# -----------
+# Compare the output of the given statement on all the nodes of the cluster.
+#
+# Parameters
+# ----------
+# $galera_diff_statement
+#   Statement for which the output would be compared.
+# 
+# $galera_diff_database
+#   Database against which the above statement would be executed.
+#   (Default : test)
+#
+# $galera_diff_servers
+#   Comma separated list of servers to executed the diff statement on. If not
+#   set, a list of servers will be generated based on $galera_cluster_size.
+#
+# $galerra_debug
+#   Print debug information.
