  25 ;;; Commentary:
  26 ;;
  27 ;; The GNU Automake tool is the first step towards having a really
  28 ;; good project management system.  It provides a simple and concise
  29 ;; look at what is actually in a project, and records it in a simple
  30 ;; fashion.
  31 ;;
  32 ;; project-am uses the structure defined in all good GNU projects with
  33 ;; the Automake file as it's base template, and then maintains that
  34 ;; information during edits, automatically updating the automake file
  35 ;; where appropriate.
