Use: "gen",
|
|
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`,
