+non-interactive shells such as cron jobs can source the file and make
+passwordless ssh connections.  In addition, when keychain runs, it
+verifies that the key files specified on the command-line are known to
+ssh-agent, otherwise it loads them, prompting you for a password
+if necessary.")

This is my first patch. Feedback, suggestions welcomed.

I'll have more coming as I add softwares I use that aren't included yet.

Thanks,
