// Creating a client

// Usage example:

//   import "google.golang.org/api/language/v1"
//   ...
//   ctx := context.Background()
//   languageService, err := language.NewService(ctx)
//
// In this example, Google Application Default Credentials are used for authentication.

// Other authentication options

// By default, all available scopes (see "Constants") are used to authenticate. To restrict scopes, use option.WithScopes:
//
//   languageService, err := language.NewService(ctx, option.WithScopes(language.CloudPlatformScope))
//
// To use an API key for authentication (note: some APIs do not support API keys), use option.WithAPIKey:
//
//   languageService, err := language.NewService(ctx, option.WithAPIKey("AIza..."))
//
// To use an OAuth token (e.g., a user token obtained via a three-legged OAuth flow), use option.WithTokenSource:
//
//   config := &oauth2.Config{...}
//   // ...
//   token, err := config.Exchange(ctx, ...)
//   languageService, err := language.NewService(ctx, option.WithTokenSource(config.TokenSource(ctx, token)))
