Attached is a patch that adds nginx and postgresql recipes. I haven't had a chance to test em within deprec yet (before doing the diff I made a few quick changes, mostly just changing the puts to render_template_to_file) , but worked fine in my own app. I haven't made any changes to the rest of deprec, as I'm not sure how you want to integrate them...
I integrated it the following way, but it may want to be rethought so you could do set :db, :postgresql and set :webserver, :nginx and have it automatically use the right one, or maybe you want to have the deprec config generator prompt the user to what DB and what webserver they want, and generate the relevant config stub for them.
