Example Emacs init using Elpaso. (For my friend Raoul)

init.el

;;----------------------------------------------------------------------
;; Elpaso package manager

;; Bootstrap it outside of Emacs: these commands will install cask and elpaso,
;; respectively, to ~/.emacs.d/elpa.
;;
;; $ cd builds  # go somewhere where you usually build software.
;; $ git clone https://github.com/cask/cask && make -C cask install
;; $ git clone https://github.com/commercial-emacs/elpaso && make -C elpaso install

(package-initialize)  ; add all packages in `elpa/` to `load-path`.
(require 'elpaso)     ; now we can load elpaso.

;; Let elpaso handle use-package ensures (i.e., installs).
(require 'use-package)
(setq use-package-ensure-function 'elpaso-use-package-ensure-function)

;;----------------------------------------------------------------------
;; Your use-package invocations

(use-package projectile
  :ensure t  ;; this ensures `projectile` is installed (and elpaso will handle it).
  :config
  (projectile-mode +1))
