** Backups
Borrowed from Sacha Chua
https://github.com/sachac/.emacs.d/
This is one of the things people usually want to change right away. By default, Emacs saves backup files in the current directory. These are the files ending in =~= that are cluttering up your directory lists. The following code stashes them all in =~/.emacs.d/backups=, where I can find them with =C-x C-f= (=find-file=) if I really need to.

(setq backup-directory-alist '(("." . "~/.emacs.d/backups")))

Disk space is cheap. Save lots.

** Prompt for 'y or n' instead of 'yes or no'
Because typing out "yes" and "no" is irritating.

* Custom settings
Store options set via =customize-*= in a separate file (Emacs stores
them in =init.el= by default).
#+name: custom-settings

#+END_SRC
* Auto-loading elisp files
Any elisp files dropped into =~/.emacs.local.d/= will be
automatically loaded.
I usually use this is a testing ground for new configuration before
adding it here, and also for any personal / sensitive configuration.
#+name: auto-load
#+BEGIN_SRC emacs-lisp
(defun my/load-elisp-directory (path)
(let ((file-pattern "\\.elc?$"))
(when (file-directory-p path)
(mapcar (lambda (lisp-file)
(load-file lisp-file))
(directory-files (expand-file-name path) t file-pattern)))))
(my/load-elisp-directory "~/.emacs.local.d")
#+END_SRC
* Configuration file layout
Here I define the emacs.el file that gets generated by the code in
this org file.
#+BEGIN_SRC emacs-lisp :tangle yes :noweb no-export :exports code
