;; Description: Emacs configuration file (in emacs lisp)

;; TODO: clean up backages (prefer ELPA to AUR and archlinux packages); also denote which
;;       source is being used after require or autoload sexp's.
;;        E.g (require 'pkg) ;; PKG_SRC
;;            (autoload ...) ;; PKG_SRC
;;       For packages that are installed through the ELPA (and thus they are loaded
;;       auto-magically) that do not require any changes to this file (.emacs) and/or
;;       are changed using customize simply note (in a comment) at the beginning of this file
;;       the package

;; ELPA packages that do not require modification of this file other then Customize
;;  * psgml
;;  * caml (required by tuareg)
;;  * tuareg
;;  * project-mode
;;  * register-list

;; ELPA packages configured explicitly below:
;;  * php-mode
;;  * python-mode
;;  * ipython
;;  * lua-mode
;;  * erlang
;;  * clojure-mode
;;  * ..more
;; TODO: document and cleanup file; specifically remove requires and autoloads of packages
;;       that are autoloaded by package.el's package-initialize. Also ensure that each
;;       file type and respective mode are added to auto-mode-alist along with a call to
;;       autoload to give the user documentation. Eg:
;;         (autoload 'foo-mode "foo" "Some documentation." t)
;;         (add-to-list 'auto-mode-alist '("\\.foo\\'" . foo-mode))

;; Set repos for package.el
(setq package-archives '(("gnu" . "http://elpa.gnu.org/packages/")

;; This needs to be a the start of ~/.emacs since package-initialize is run after the user
;; init file is read but before after-init-hook. It autoloads packages installed by
;; package.el including updating the load-path and running/loading/requiring
;; pkgname-autoload.el for all packages (where pkgname is replaced with the appropriate
;; package name). To disable package.el's autoloading functionality use:
;;    (setq package-enabled-at-startup nil)
;; The reason to use package-initialize here is so one can modify the installed modules
;; later in this .emacs file but still retain the autoloading functionality of package.el
(package-initialize)
