;; erlang-start.el --- Load this file to initialize the Erlang package.
;; Copyright (C) 1998 Ericsson Telecom AB
;; Author: Anders Lindgren
;; Version: 2.3
;; Keywords: erlang, languages, processes
;; Created: 1996-09-18
;; Date: 1998-03-16
;;; Commentary:
;; Introduction:
;; ------------
;;
;; This package provides support for the programming language Erlang.
;; The package provides an editing mode with lots of bells and
;; whistles, compilation support, and it makes it possible for the
;; user to start Erlang shells that run inside Emacs.
;;
;; See the Erlang distribution for full documentation of this package.
;; Installation:
;; ------------
;;
;; Place this file in Emacs load path, byte-compile it, and add the
;; following line to the appropriate init file:
;;
;; (require 'erlang-start)
;;
;; The full documentation contains much more extensive description of
;; the installation procedure.
;; Reporting Bugs:
;; --------------
;;
;; Please send bug reports to the following email address:
;; support@erlang.ericsson.se
;;
;; Please state as exactly as possible:
;; - Version number of Erlang Mode (see the menu), Emacs, Erlang,
;; and of any other relevant software.
;; - What the expected result was.
;; - What you did, preferably in a repeatable step-by-step form.
;; - A description of the unexpected result.
;; - Relevant pieces of Erlang code causing the problem.
;; - Personal Emacs customisations, if any.
;;
;; Should the Emacs generate an error, please set the emacs variable
;; `debug-on-error' to `t'. Repeat the error and enclose the debug
;; information in your bug-report.
;;
;; To set the variable you can use the following command:
;; M-x set-variable RET debug-on-error RET t RET
;;; Code:
;;
;; Declare functions in "erlang.el".
