Enforcing standard configuration

I'm looking for some input on what tools/methods people are using to enforce standard config.

I don't exactly mean a golden config, I just mean ensuring that all your devices have certain lines of config applied.

We do have solarwinds but it's baseline configuration is pretty useless in this regards as instead of just checking that all the lines exist, it matches those that also do not exist and says there is a mismatch.

I am also in the process of trying to script it, just working out the best method at the moment.

So how does everyone else go about doing this?
