+# extract-shadow-warrior.sh, by B. Watson (yalhcru@gmail.com).
+
+# Licensed under the WTFPL: Do WTF you want with this. See
+# http://www.wtfpl.net/txt/copying/ for details.
+
+# This file is part of the SlackBuilds.org jfsw_registered_data build,
+# but you're welcome to use it for any other purpose (that's why I made
+# it a standalone script).
+
+# Extracts the game data from bin/cue of Shadow Warrior for DOS, as found
+# in the zip file from https://archive.org/details/ShadowWarriorUSA. The
+# tool that handles bin/cue files is bchunk, but sadly it doesn't properly
+# handle bin/cue where each track is in a separate bin file... so we
+# help it along by chopping up the .cue file.
+
+# We expect a single argument: the name of the .cue file. Output will be
+# a set of .iso and .wav files in the current directory, named track01.iso
+# and track02.wav through track14.wav, plus a set of converted track02.ogg
+# through track14.ogg, if the oggenc command is found on $PATH.
+
+# When we're finished, the files will take up around 900MB of space,
+# so plan accordingly.
+
+# Note: converting the same wav file to ogg with oggenc multiple times,
+# does not give identical ogg files. It *does* however give the same
+# sized file every time (down to the byte). Really only matters if you're
+# debugging this script, I guess.
