+/*  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.
