Can you translate a line of bash into plain english for me?

From Mr. Laureth, who once made a living on the UNIX command line:

“While I used csh instead of bash, when I did shell scripting, I believe it does this:

1. Pause for 1 second

2. Check if openvpn is running; if it is, kill it.

3. If someone logs on, add the username and password to the file /tmp/openvpncl/auth.conf .

4. Start openvpn.

5. Loop back to the sleep.

Either I’m way off, or this is a way to collect usernames and passwords of third parties. It’s hard to come up with a legitimate reason to do this.”

Thanks. No not a way to collect passwords. It starts up openvpn and runs on dd-wrt (http://www.dd-wrt.com/). You have to write your user/pass to a temporary file every time it boots because it doesn’t save it permanently.

I just wanted to know exactly what these few lines did. Thanks!
