+
+	This sample customization script can be used to automatically configure
+	the NIM nimsh (NIM service handler).  It will also configure NIMSH to 
+	use OpenSSL in the NIM environment.
+
+	It assumes that the openssl software has already been installed on the 
+	node.
+
+	This script also assumes that you have run "nimconfig -c" on the NIM 
+	master for the nodes.  
+
+	This script should only be run on AIX standalone (diskfull) cluster compute 
+	nodes. It should NOT be run on the xCAT management node, service nodes or
+	diskless nodes.
+
+	Note:  This script will also remove the .rhosts file (actually back it up).
+	If you don't want it removed then comment out those lines.
