# Dist layout reference

The forge output for a given MuJoCo version/ref lives under `dist/<ver>/`.

## Directory layout (typical)

```text

  mujoco.js
  mujoco.wasm
  pthreads/                # optional (when built with --pthreads)
    mujoco.js
    mujoco.wasm
    *.worker.*             # Emscripten thread worker stubs (name varies)
  abi/
    exports.lst
    exports_check.json
    exports_check.pthreads.json  # optional (pthreads export check output)
    exports_report_funcs.md
    nm_symbols.json
    wrapper_exports_funcs.json
    functions_introspect_like.json
