// This file is a helper for those doing _manual_ testing of "terraform login"
// and/or "terraform logout" and want to start up a test OAuth server in a
// separate process for convenience:
//
//    go run ./command/testdata/login-oauth-server/main.go :8080
//
// This is _not_ the main way to use this oauthserver package. For automated
// test code, import it as a normal Go package instead:
//
//     import oauthserver "github.com/hashicorp/terraform/internal/command/testdata/login-oauth-server"
