;;; Commentary:
;; This file provides the stuffs to setup the environment for building
;; emacs-w3m and the installer for non-UNIX systems.
;;; How to install:
;; ( These document is a simple summary of README. For more detail,
;; see the original. )
;; In order to install emacs-w3m to non-UNIX systems which lack an
;; ability to execute `configure' script or have no `make' utility,
;; execute this command.
;; emacs -batch -q -no-site-file -l w3mhack.el NONE -f w3mhack-nonunix-install
;; When required packages, such as APEL, are installed into unusual
;; places, the installer may miss them. In this case, it is necessary
;; to tell their places to the installer, as follows:
;; emacs -batch -q -no-site-file -l w3mhack.el //c/share/apel://c/share/flim -f w3mhack-nonunix-install
;; If you want to install programs and icons to unusual directories,
;; edit this file and set your request to `w3mhack-nonunix-lispdir'
;; and `w3mhack-nonunix-icondir'.
