The script is self-documenting:

NAME
    dvd2concat - create a concat script for a DVD title

SYNOPSIS
    tools/dvd2concat *path/to/dvd/structure* > *file.concat*

DESCRIPTION
    This script uses lsdvd to produce concat script for a DVD title. The
    resulting script can be used to play the DVD using ffplay, to transcode
    it using ffmpeg or any other similar use.

    *path/to/dvd/structure* is the path to the DVD structure hierarchy; it
    normally contains a directory named VIDEO_TS. It must not be encrypted
    with CSS.

    *file.concat* is the output file. It can be used as an input to ffmpeg.
    It will require the -safe 0 and -protocol_whitelist file,subfile,concat
    options.

Then you need to peruse the documentation about concat scripts:
