;; This is my .emacs.
;; There are many like it, but this one is mine.
;;
;;  (Well, it *was*.... but then I adopted starter-kit, because why not?)
;;
;; 2014/03/31 - Well, it isn't actually named .emacs anymore; but this is the
;;              real initialization file, for code and junk. init.el just
;;              does the package load stuff now. Don't know why package init
;;              was built to work like it does in emacs 24, but oh well.
;; 
;;              Abandoning el-get for ELPA; ELPA seems more official and more
;;              like what I want anyhow. Of course, this needs the
;;              two-file-dance, but it's worth it. Much of the infrastructure
;;              is based on starter-kit:
;;
;;                  https://github.com/eschulte/emacs24-starter-kit/blob/master/starter-kit.org
;;
;; 2014/03/21 - Started to re-work it based on https://github.com/dimitri/emacs-kicker/blob/master/init.el
;;
;;              This emacs file has been around for a very long time, and it
;;              has accumulated a lot of stuff. I'd like to try to clean it
;;              up a little bit.... 
;;
;;              ...turns out that lots of the customization still makes
;;              sense. But fetching the packages is still the hard part.
