;;; File: erlang_appwiz.el
;;; Author: Johan Bevermyr
;;; Created: Tue Dec 9 13:14:24 1997
;;; Purpose: Adds a simple application wizard to erlang.el.
;; OBS! Must be loaded before the erlang.el file is loaded.
;; Add the following to your .emacs file before erlang.el is loaded.
;;
;; (load "erlang_appwiz" t nil)
;;
;; Customisation of makefile generation:
;;
;; The templates for generating makefiles are stored in the
;; variables erlang-skel-makefile-src and erlang-skel-makefile-middle.
;;
;; These can be modified by setting the variables before or after this
;; file is loaded.
;;
;; For example, to generate OTP-style make files:
