You can also prevent different flags from being provided together if they represent mutually
exclusive options such as specifying an output format as either `--json` or `--yaml` but never both:
```go
rootCmd.Flags().BoolVar(&u, "json", false, "Output in JSON")
rootCmd.Flags().BoolVar(&pw, "yaml", false, "Output in YAML")
rootCmd.Flags().BoolVar(&ofJson, "json", false, "Output in JSON")
rootCmd.Flags().BoolVar(&ofYaml, "yaml", false, "Output in YAML")
rootCmd.MarkFlagsMutuallyExclusive("json", "yaml")
```
