My $HOME/.emacs file

.emacs

; I use Emacs on three different platforms and I want to use the same init file. 
; So, this file lives as $HOME/.emacs and is just a pointer to an init file in my Dropbox. 
; The machine specific automatic customizations are saved here nonetheless.

; The real dot-emacs file is in ~/Dropbox/myemacs/init.el
(setq my-emacs-root (expand-file-name "~/Dropbox/myemacs/"))
(add-to-list 'load-path my-emacs-root)
(load-file (concat  my-emacs-root "init.el"))

; automatic customization
(custom-set-variables
 ;; custom-set-variables was added by Custom.
 ;; If you edit it by hand, you could mess it up, so be careful.
 ;; Your init file should contain only one such instance.
 ;; If there is more than one, they won't work right.
