Usage

Execute this script during the build of your project. It will generate full and minified scripts including source maps, which you will be able to load on your web page alongside with @babel/standalone and the generated babel-helpers. Specify the output directory and optionally the base name of the files, for example:

generate-babel-polyfills dist

The full and minified files with source maps will be written to the specified directory. The extension ".js" will be appended to the file name.
