;;; This script by Paul Biggar, available at https://gist.github.com/pbiggar/6323088a31d689c61a24
;;;
;;; This converts Evernote files into plaintext (not really markdown), so you can move your stuff out of evernote into a markdown editor.
;;;
;;; First, export your Evernotes, using File -> export notes. Export them into "My Notes.enex".
;;; copy this file into the same direcory as "My Notes.enex".
;;;
;;; To run this file, you'll need some dependencies, but they should only take a moment to install.
;;;   leinigen: On OSX, use "brew install leiningen".
;;;   lein-exec: From the terminal, run `mkdir ~/.lein; echo '{:user {:plugins [[lein-exec "0.3.5"]]}}' > ~/.lein/profiles.clj
