# `mix collector.package_source`

Stores your app's `lib/**/*.ex` inside the collector dependency's
build, so a release, which ships no source files, can still send the
lines around each frame of your code.

Run it right before `mix release`:

    MIX_ENV=prod mix collector.package_source
    MIX_ENV=prod mix release

Options:

  * `--root` — the app's directory (default: the current one).
  * `--out` — where to write (default: collector's `priv/source.etf`
    in the current build).
