```
val make : ?cwd:string -> ?environment:(string * string) list -> command -> t
```

Describe a program without I/O. `Exec` preserves argv; `Shell` explicitly requests the daemon's configured shell. `cwd` must be absolute. Validation occurs at admission. With no arguments, `Exec` uses a fixed `/bin/sh` trampoline because tmux treats a single argument as shell code. `Default` follows tmux defaults on creation and reuses the previous command on respawn.

## Parameters

- `cwd?` (`string`)
- `environment?` (`(string * string) list`)
- `arg1` (`command`)
