It's a Java-based tool. This package, in the spirit of the
yuicompressor <http://pypi.python.org/pypi/yuicompressor/> package,
provides a simple way to install and use the the Closure compiler from
Python, bundling the
closure.jar with the Python package.
I recommend looking at webassets for your CSS/JS compression needs.
YYYYMMDD of this package will bundle the corresponding
version of the compiler (Closure uses the build date as the version).
If you want a new version to be uploaded, open a ticket at the Github page.
