Thanks to everyone who replied to my questions yesterday. I gleaned some
very useful information from the conversations.
Using some of the suggestions, I kludged together another script. I'm
still fine tuning it. It works great for A and CNAME records, but I'm
tweaking the MX and NS record types.
Comments and critiques are appreciated.
