    `makeScriptWriter` returns a derivation which creates an executable script.

    # Inputs

    config (AttrSet)
    : `interpreter` (String)
      : the [interpreter](https://en.wikipedia.org/wiki/Shebang_(Unix)) to use for the script.
    : `check` (String)
      : A command to check the script. For example, this could be a linting check.
    : `makeWrapperArgs` (Optional, [ String ], Default: [])
      : Arguments forwarded to (`makeWrapper`)[#fun-makeWrapper].

    `nameOrPath` (String)
    : The name of the script or the path to the script.

      When a `string` starting with "/" is passed, the script will be created at the specified path in $out.
      I.e. `"/bin/hello"` will create a script at `$out/bin/hello`.

      Any other `string` is interpreted as a filename.
      It must be a [POSIX filename](https://en.wikipedia.org/wiki/Filename) starting with a letter, digit, dot, or underscore.
      Spaces or special characters are not allowed.

    `content` (String)
    : The content of the script.

    :::{.note}
    This function is used as base implementation for other high-level writer functions.

    For example, `writeBash` can (roughly) be implemented as:

    ```nix
    writeBash = makeScriptWriter { interpreter = "${pkgs.bash}/bin/bash"; }
    ```
    :::

    # Examples
    :::{.example}
    ## `pkgs.writers.makeScriptWriter` dash example

    ```nix-repl
    :b makeScriptWriter { interpreter = "${pkgs.dash}/bin/dash"; } "hello" "echo hello world"
    -> /nix/store/indvlr9ckmnv4f0ynkmasv2h4fxhand0-hello
    ```

    The above example creates a script named `hello` that outputs `hello world` when executed.

    ```sh
    > /nix/store/indvlr9ckmnv4f0ynkmasv2h4fxhand0-hello
    hello world
