## Bundled lensfun calibration data

The Erlang term file `priv/lensfun/lensfun.etf` is generated from the
[lensfun](https://github.com/lensfun/lensfun) project's XML calibration
database. That database is distributed under the

The lensfun reference C library is licensed under LGPL v3. This
package does not link to or distribute that library; it re-implements
the calibration math in Elixir.
