I think you're talking about something else. I'm talking about set up and configuration of these tools and servers. Other people's scripts may read those configuration files and apply them but it is the config itself that I do on my own. Even then, I sometimes edit those build scripts if they don't do what I want and I just need something customized. If some other tool set all that up for me, I'd never know how to do it or I'd have to learn it anyway, negating the need for this tool in the first place.
