/**
 * Convenience script to harmonize cache directories across various
 * tooling such as eslint and jest.
 *
 * Recently more & more tools like babel-loader tend to cache in
 * node_modules/.cache (@link https://github.com/avajs/find-cache-dir)
 * It's possible too, but keeping a cache folder at the root simplifies
 * the cache management on CI
