;;; Commentary:
;;
;; Code generator for Makefiles.
;;
;; Here is how it should work:
;; 1) Collect information about the project and targets
;; 2) Insert header into the Makefile
;; 3) Insert basic variables (target/source)
;; 4) Conditional
;;    a) Makefile
;;       1) Insert support variables (compiler variables, etc)
;;       2) Insert VERSION and DISTDIR
;;       3) Specify top build dir if necessary
;;       4) Specify compile/link commands (c, etc)
;;       5) Specify dependency files
;;       6) Specify all: target
;;       7) Include dependency files
;;       8) Insert commonized target specify rules
;;       9) Insert clean: and dist: rules
;;    b) Automake file
;;       1) Insert distribution source variables for targets
;;       2) Insert user requested rules
