$ cargo run --bin merge_xray_quadtrees -- --help
merge_xray_quadtrees 0.1.0
Merge partial xray quadtrees. We assume that the root of each quadtree belongs to the same level of the final quadtree

USAGE:
    merge_xray_quadtrees --output_directory <output-directory> [input-directories]...

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

OPTIONS:
        --output_directory <output-directory>
            Directory where to write the merged quadtree. Does *not* have to be disjoint from input_directories

ARGS:
    <input-directories>...    Directories with, possibly multiple, partial xray quadtrees

With new arguments:

$ cargo run --bin merge_xray_quadtrees -- --help
merge_xray_quadtrees 0.1.0
Merge partial xray quadtrees. We assume that the root of each quadtree belongs to the same level of the final quadtree

USAGE:
    merge_xray_quadtrees [OPTIONS] --output-directory <output-directory> [input-directories]...

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

OPTIONS:
        --output-directory <output-directory>
            Directory where to write the merged quadtree. Does *not* have to be disjoint from input_directories

        --tile-background-color <tile-background-color>    Tile background color [default: white]
        --tile-size <tile-size>                            Tile size [default: 256]

ARGS:
    <input-directories>...    Directories with, possibly multiple, partial xray quadtrees

Or do you prefer to have both output_directory and input_directories as positional arguments? i.e.

$ cargo run --bin merge_xray_quadtrees -- --help
merge_xray_quadtrees 0.1.0
Merge partial xray quadtrees. We assume that the root of each quadtree belongs to the same level of the final quadtree

USAGE:
    merge_xray_quadtrees [OPTIONS] <output-directory> [input-directories]...

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

OPTIONS:
        --tile-background-color <tile-background-color>    Tile background color [default: white]
        --tile-size <tile-size>                            Tile size [default: 256]

ARGS:
    <output-directory>        Directory where to write the merged quadtree. Does *not* have to be disjoint from
                              input_directories
    <input-directories>...    Directories with, possibly multiple, partial xray quadtrees

Or

$ cargo run --bin merge_xray_quadtrees -- --help

        --output-directory <output-directory>

        --tile-background-color <tile-background-color>    Tile background color [default: white]
