Hi. I’m trying to use [Eio](https://github.com/ocaml-multicore/eio) on Linux. The following
```ocaml
Eio.Process.run proc_mgr ["path/to/main.exe"; "-arg1 value1"; "-arg2 value2"];
```
yields
```shell
path/to/main.exe: unknown option '-arg1 value1'.
Uncaught exception:
Eio.Io Process Child_error Exited (code 2),
running command: path/to/main.exe "-arg1 value1" "-arg2 value2"
```
which I assume to be the case due to the quotation marks in the arguments, since
```auto
$ path/to/main.exe -arg1 value1 -arg2 value2
```
is successful and yields the expected output.
If my assumption is correct, is there any way to avoid the quotation marks? I was not able not find this in the [API](https://ocaml-multicore.github.io/eio/eio/Eio/Process/index.html).

Each separate argument should be its own item in the argument list:
```auto
Eio.Process.run proc_mgr ["path/to/main.exe"; "-arg1”; “value1"; "-arg2”; ”value2"];
```

Or rather, each separate ‘word’, even if you would normally consider part of the same command-line flag.

Of course! Thanks a lot 🙂
