This really looks like something I should be able to find on Google, but for some reason I can't make heads or tails of it. There's the EDITOR environment variable, the ipy_user_conf.py file, the ipythonrc file, some weird thing about running gvim in server mode and a bunch of other stuff I can't wrap my head around (probably because of lack of sleep).
Is there a guide somewhere I can follow, or maybe someone can just outline the steps I need to take?
