Short: "gen is a 996.icu license generator-command.",
Long: `gen is a 996.icu license generator-command,
it is used to generate various open-source licenses including MIT, Apache, etc.
More importantly, the main purpose of this tool is to incorporate those aforesaid licenses into
a brand new license: 996.icu, defined by this repository.
How to use gen:
# Generate a pure open-source license, take MIT for example:
gen-license-go mit
# Incorporate a open-source(MIT) license into the 996icu license with a specific-language(en-us or zh-cn) template:
gen-license-go gen mit --996icu en-us`,

// Cobra supports Persistent Flags which will work for this command

// genCmd.PersistentFlags().String("foo", "", "A help for foo")

// is called directly, e.g.:
// genCmd.Flags().BoolP("toggle", "t", false, "Help message for toggle")
