# BusyBox for CST-Agent

## Windows (`busybox.exe`)

Built from **busybox-w32**:
https://github.com/rmyorston/busybox-w32.git

```bash
./scripts/build_third_party_mingw.sh busybox-w32
# → third_party/busybox/busybox.exe
```

Ship next to `cst-agent.exe`. License: GPLv2 (`LICENSE.busybox`).

## Linux / Termux (optional side-by-side `busybox`)

Upstream mirror:
https://github.com/mirror/busybox.git

```bash
./scripts/build_third_party_mingw.sh busybox-unix
# → third_party/busybox/busybox
```

On Unix, `run_shell` prefers `CST_SHELL`, then `<exe_dir>/busybox`, then
`$PREFIX/bin/sh` (Termux), then `/bin/sh`.
