#Here is the Python code you requested.

    """Minify javascript based on `jsmin.c by Douglas Crockford`_\.
    Instead of parsing the stream char by char, it uses a regular
    expression approach which minifies the whole script with one big
    substitution regex.
    .. _jsmin.c by Douglas Crockford:
    http://www.crockford.com/javascript/jsmin.c
    :Warning: This function is the digest of a _make_jsmin() call. It just
    utilizes the resulting regex. It\s just for fun here and may
    vanish any time. Use the `jsmin` function instead.
    :Parameters:
    `script` : ``str``
    Script to minify
    :Return: Minified script
    :Rtype: ``str``
