There were lots of people who could read this for a living. I was more or less able to at one point. Wow, I'm glad that I don't have to anymore, though, in much the same way I'm glad I never had to learn TECO.

TECO isn't actually that bad, and I'd argue that it's roughly on the level of vi in complexity. I learned it just for fun, and found it more powerful than vi. I was using videoteco when I learned it, and I recommend it to anyone that also wants to play around with this.

I definitely would never want to go back to configuring sendmail though. Unlike TECO it doesn't provide anything compared to a modern mail product.
