/* The package defintion for an OpenRA out-of-tree mod.
It shares code with `engine.nix` by what is defined in `common.nix`.
To build an out-of-tree mod it needs the source code of the engine available,
and they each need to be build with a specific version or fork of the engine,
so the engine needs to be supplied as an argument as well.
The engine is relatively small and quick to build, so this is not much of a problem.
Building a mod will result in a wrapper script that starts the mod inside the specified engine.
