+how to use the ssh login passwordless script
+============================================
+
+This script helps configure passwordless SSH between two machines.
+
+SCOPE
+The script itself is nothing more than putting in line the few commands needed to set up this rather simple, if annoying, procedure and should keep
+you focusing on the important stuff rather than remembering syntax details.
+
+USAGE
+You must place this script on the client machine and run it. You can provide two arguments on the command line, the first one is the hostname that will
+accept passwordless login and the second one is the username on that machine.
+
+If the second argument is ommited, the username will default to the username on the client machine and if both arguments are omitted, they will be asked interactively.
