+#+TITLE: Emacs Configuration for Alan Pearce
+#+OPTIONS: ^:nil
+#+PROPERTY: results silent
+#+PROPERTY: eval no-export
+#+PROPERTY: header-args :comments link
+* Introduction
+This is a living document, detailing my Emacs configuration using org-mode
+* Basics
+** Startup
+Open Emacs with just a plain window.  No graphics or messages, please!

+(setq file-name-handler-alist nil)

+#+END_SRC
+
+** Scratch buffers
+I usually use scratch buffers for any sort of text.  If I need a
+programming mode in one, then I’ll just call it manually.  I also like
+the buffer to be empty.

+* Customize
+I don’t really like using customize for normal configuration.
+Instead, I use it for things that get saved automatically.  That’s why
+I use a different file, which is ignored by the VCS.  It also means
+that it’s not important whether the file exists or not, which is why I

+
+By default, Emacs displays page breaks as ^L.  Lines look much nicer.

+* Tangling
+
+Taken from [[https://github.com/larstvei/dot-emacs/blob/master/init.org][larstvei/dot-emacs]].  I changed it so that it would work with
+my current dotfiles repository structure and work asynchronously,
+thanks to [[https://github.com/jwiegley/emacs-async][jwiegley/emacs-async]].
+
+We can use =C-c C-v t= to run =org-babel-tangle=, which extracts the
+code blocks from the current file into a source-specific file (in this
+case a =.el=-file).
+
+To avoid doing this each time a change is made we can add a function
+to the =after-save-hook= ensuring to always tangle and byte-compile
+the =org=-document after changes.
