#!/usr/bin/env bash

# ripdvd.sh -
# This script is an attempt to make it easier for users to make backups
# of their DVD discs to store on their systems for convenient
# usage so that the original discs can stay in their protective cases to
# prevent damage.

# WARNING
# This script was not created for any type of illegal activities. The script
# author is in no way responsible and will not be held liable for activities
# the user does with this script.

# LEGAL
# In some countries, it is NOT legal to create copies of optical media,
# even for backup purposes. Also, in some countries, using tools/libraries to
# defeat copy protection on optical media to create backups is NOT legal.
#
# Use this script and dependency tools at your own risk.

# DEPENDENCIES
# This script was created on Ubuntu 16.04, and the following package are
# required for smooth operation:
#
# coreutils    (cut, mkdir, rm, ls)
# grep         (grep)
# libdvdread4  (library used by dvdbackup to read DVD media)
# libdvd-pkg   (downloads libdvdcss source, compiles it locally, and installs to your system)
# dvdbackup    (the workhorse behind this script)
# genisoimage  (the prettifier)

# NOTES
# This script uses BASH's "type -P" command to find needed dependencies in
# the system path. It is far more accurate and faster than using "which" to
# find things. As long as BASH is installed, there shouldn't be any problems.
