help_text="Usage: generate-unique-machine-values.sh

General options:
    --count, -n, -c <count>         Number of serials to generate
    --model, -m <model>             Device model, e.g. 'iMacPro1,1'
    --csv <filename>                Optionally change the CSV output filename.
    --tsv <filename>                Optionally change the TSV output filename.
    --output-bootdisk <filename>    Optionally change the bootdisk qcow output filename. Useless when count > 1.
    --output-env <filename>         Optionally change the bootdisk env filename. Useless when count > 1.
    --output-dir <directory>        Optionally change the script output location.
    --width <string>                Resolution x axis length in pixels (default 1920)
    --height <string>               Resolution y axis length in pixels (default 1080

    --master-plist-url <url>        Specify an alternative master plist, via URL.
    --master-plist | --custom-plist <filename>
                                    Optionally change the input plist. Placeholders:
                                        {{DEVICE_MODEL}}, {{SERIAL}}, {{BOARD_SERIAL}},
                                        {{UUID}}, {{ROM}}, {{WIDTH}}, {{HEIGHT}}

    --help, -h, help                Display this help and exit
    --plists                        Create corresponding config.plists for each serial set.
    --bootdisks                     [SLOW] Create corresponding boot disk images for each serial set.

Example:
    ./generate-unique-machine-values.sh --count 1 --model='iMacPro1,1' --plists --bootdisks

        The above example will generate a
            - serial
            - board serial
            - uuid
            - MAC address
            - ROM value based on lowercase MAC address
            - Boot disk qcow image.
            - config.plist

Notes:
    - Default is 1 serial for 'iMacPro1,1' in the current working directory.
    - Default output is CSV, whereas setting the TSV option will output as tab-separated.
    - CSV is double quoted.
    - If you do not set a CSV filename, the output will be sent to the output-dir.
    - If you do not set an output-dir, the current directory will be the output directory.
    - Sourcable environment variable shell files will be written to a folder, 'envs'.
    - config.plist files will be written to a folder, 'plists'.
