;;; Commentary:
;;
;; NOTE: EDE Simple Projects are considered obsolete. Use generic
;; projects instead. They have much better automatic support and
;; simpler configuration.
;;
;; A vast majority of projects use non-EDE project techniques, such
;; as hand written Makefiles, or other IDE's.
;;
;; The EDE-SIMPLE project type allows EDE to wrap an existing mechanism
;; with minimal configuration, and then provides project-root
;; information to Semantic or other tools, and also provides structure
;; information for in-project include header discovery, or speedbar
;; support.
;;
;; It will also support a the minimal EDE UI for compilation and
;; configuration.
;; @todo - Add support for cpp-root as an ede-simple project.
;; @todo - Allow ede-simple to store locally.
