;;; dot.emacs --- Summary
;;; This package will enable us to use multiple emacs startup
;;; configuration(startkit in this package) and switch between
;;; these configuration just by change a single environment
;;; variable (EMACS_STARTKIT).
;;;
;;; Currently, we have test it with following:
;;; - doom-emacs
;;; - spacemacs
;;; - frontmacs
;;; - ohai-emacs
;;; - graphene
;;; - prelude
;;;
;;; Commentary:
