    //          note 1: Relies on file_get_contents which does not work in the browser, so Node only.
    //          note 2: Keep in mind that in accordance with PHP, the whole file is buffered and then
    //          note 2: hashed. We'd recommend Node's native crypto modules for faster and more
    //          note 2: efficient hashing
    //       example 1: sha1_file('test/never-change.txt')
    //       returns 1: '0ea65a1f4b4d69712affc58240932f3eb8a2af66'
