+# actual path to the crate. This breaks our deterministic builds as we depend
+# on a copy of rust-lightning via a path. We insert this shim between cargo and
+# rustc and edit the metadata tag for rust-lightning.
+# While we could just set RUSTFLAGS="-C metadata=42", this would break if we
+# ever (indirectly) depend on multiple versions of the same crate.
