Concrete5.5. apparently has some amazing ability to let you put your site settings into a file before installation so it will just automatically use those, instead of you having to fill out the form with the database/user information. Does anyone know what format this file needs to be in, what it needs to be called, and where you place it?

Also, if I want to just run the installation from the command-line (which the release notes say is now possible), how do I go about doing that?
