;;; Commentary:

;; The Idea:
;; Let XEmacs report interesting aspects of how it was built.

;; The Concept:
;; User creates an XEmacs Build Report by just calling
;; M-x build-report
;; which will initialize a mail buffer with relevant information
;; derived from the XEmacs build process. Point is left at the
;; beginning of the report for user to input some personal notes and
;; send the report.

;; The Status:
;; This is the first `Proof of Concept'.

;; The Author:
;; Adrian Aichner, Teradyne GmbH Munich, Sun., Apr. 20, 1997.

;;; Code:

(require 'config)
(require 'custom)
(require 'cl)
(provide 'build-report)

;;; Constant definitions used internally by `build-report'.  These are not
;;; anticipated to be changed by users of `build-report'.
;;; If users do need to change the value of any of these, they need to do
;;; it after `build-report' has been loaded (not just required).  Please
;;; report it to the maintainers of `build-report' when you think you
;;; need to do this.
