+// +build dummy
+
+// This file is part of a workaround for `go mod vendor` which won't vendor
+// C files if there's no Go file in the same directory.
+// This would prevent the crypto/secp256k1/libsecp256k1/include/secp256k1.h file to be vendored.
+//
+// This Go file imports the c directory where there is another dummy.go file which
+// is the second part of this workaround.
+//
+// These two files combined make it so `go mod vendor` behaves correctly.
+//
+// See this issue for reference: https://github.com/golang/go/issues/26366
