  ## Output file names
  -Set output file names. Defaults to package name.
  +Flag `--out-name` sets the prefix for output file names. If not provided, package name is used instead.
  +
  +Usage examples, assuming our crate is named `dom`:
  ```
  +wasm-pack build
  +# will produce files
  +# dom.d.ts dom.js dom_bg.d.ts dom_bg.wasm package.json README.md
  +
  wasm-pack build --out-name index
  +# will produce files
  +# index.d.ts index.js index_bg.d.ts index_bg.wasm package.json README.md
  ```
  -This command will build the package with file names like `index.js`, `index.d.ts`, and so on.
