# Slackware build script for jfsw_registered_data

# Written by B. Watson (yalhcru@gmail.com)

# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.

# This game is offered as a free download on both Steam and GoG. It also
# was available from www.oldpcgaming.net from 2014 to late 2019, and
# has been available on archive.org since late 2018.

# 20200428 bkw: the old .7z from oldpcgaming.net has vanished along
# with the site. Switched to a CD image from archive.org, in bin/cue
# format. More work for this script to do, but as a nice bonus, we get
# the CD audio tracks installed too.

VERSION=${VERSION:-1.2}

# Depending on what was used to do the download, the %XX hex escapes
# might get interpreted or not, handle either name.

# The "source" file is a bin/cue cdrom image with multiple .bin files.
# It took some effort to get bchunk to extract this correctly, and I've
# moved the code into a separate script so that users of other distros
# can possibly make use of it. In fact it's been tested on MacOSX :)

# N.B. sandbox wrappers like sbrun or slackrepo might complain that
# /etc/mtab has been modified. We could prevent this by using the
# --no-mtab option with the mount and umount commands below, but
# if something makes the script die before it's finished, we would
# have left behind an invisible mount that could cause confusion and
# irritation later...
