+#
+# When the failover starts, ends, or is aborted, a script can be called in
+# order to perform application-specific tasks to notify the clients that the
+# configuration has changed and the master is at a different address.
+# 
+# The script is called in the following cases:
+#
+# Failover started (a slave is already promoted)
+# Failover finished (all the additional slaves already reconfigured)
+# Failover aborted (in that case the script was previously called when the
+#                   failover started, and now gets called again with swapped
+#                   addresses).
+#
+# The following arguments are passed to the script:
+#
+# <master-name> <role> <state> <from-ip> <from-port> <to-ip> <to-port>
+#
+# <state> is "start", "end" or "abort"
+# <role> is either "leader" or "observer"
+# 
+# The arguments from-ip, from-port, to-ip, to-port are used to communicate
+# the old address of the master and the new address of the elected slave
+# (now a master) in the case state is "start" or "end".
+#
+# For abort instead the "from" is the address of the promoted slave and
+# "to" is the address of the original master address, since the failover
+# was aborted.
+#
+# This script should be resistant to multiple invocations.

+# Example:

+# sentinel client-reconfig-script mymaster /var/redis/reconfig.sh
