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-dir <directory>        Optionally change the script output location
    --width <string>                Resolution x axis length in px, default 1920
    --height <string>               Resolution y axis length in px, default 1080
    --kernel-args <string>          Additional boot-args
    --input-plist-url <url>         Specify an alternative master plist, via URL
    --master-plist-url <url>        Same as above.
    --custom-plist <filename>       Optionally change the input plist.
    --master-plist <filename>       Same as above.
    --output-bootdisk <filename>    Optionally change the bootdisk filename
    --create-envs, --envs           Create all corresponding sourcable envs
    --create-plists, --plists       Create all corresponding config.plists
    --create-bootdisks, --bootdisks Create all corresponding bootdisks [SLOW]
    --help, -h, help                Display this help and exit

Additional options only if you are creating ONE serial set:
    --output-bootdisk <filename>    Optionally change the bootdisk filename
    --output-env <filename>         Optionally change the serials env filename

Custom plist placeholders:
    {{DEVICE_MODEL}}, {{SERIAL}}, {{BOARD_SERIAL}},
    {{UUID}}, {{ROM}}, {{WIDTH}}, {{HEIGHT}}, {{KERNEL_ARGS}}

Example:
    ./generate-unique-machine-values.sh --count 1 --plists --bootdisks --envs

Defaults:
    - One serial, for 'iMacPro1,1', in the current working directory
    - CSV and TSV output
    - plists in ./plists/ & bootdisks in ./bootdisks/ & envs in ./envs
    - if you set --bootdisk name, --bootdisks is assumed
    - if you set --custom-plist, --plists is assumed
    - if you set --output-env, --envs is assumed
