I'm trying to avoid people needing to even read the book. It's the difference between rolling your own WebSockets or using Pusher, for example. Some people want things to just work.
So you came here to advertise your own product in a post about mine?
You're basically deploying a thing that'll send http requests to another server which then executes specific tasks. So you've essentially replaced hubot with a web application on the end users servers.
"The commands will trigger a webhook call to your server, where the actual deployment/testing/whatever command you need takes place."
The end user still needs to run something on their servers to actually do anything for their custom commands, which is essentially what hubot scripts do, which is what my book is teaching people about.
I know, I'm not disputing anything or devaluing your book. As I said above, some people want things to just work, so we're looking to provide a service for that market. I don't know why you're getting so offended and defensive :/
