;;; Commentary:
;;
;; This software handles the maintenance of compiler and rule definitions
;; for different object types.
;;
;; The `ede-compiler' class lets different types of project objects create
;; definitions of compilers that can be swapped in and out for compiling
;; source code. Users can also define new compiler types whenever they
;; some customized behavior.
;;
;; The `ede-makefile-rule' class lets users add customized rules into thier
;; objects, and also lets different compilers add chaining rules to their
;; behaviors.
;;
;; It is important that all new compiler types be registered once. That
;; way the chaining rules and variables are inserted into any given Makefile
;; only once.
;;
;; To insert many compiler elements, wrap them in `ede-compiler-begin-unique'
;; before calling their insert methods.
;; To write a method that inserts a variable or rule for a compiler
;; based object, wrap the body of your call in `ede-compiler-only-once'
