This tool is to update gitignore-gen's tpls.
You don't need to used this tool for most of the time, I will update the gitignore-gen repo.
But, if you find you need some tpls from github's repo badly, then you shuld try this.
ignore-update src dst
eg.
ignore-update ../gitignore ../gitignore-gen
- The templates of gitignore file in gitignore-gen repo is come from GitHub's gitignore repo
- I will add more tpls for it in the future
