Installing Clique is simple with pip:
$ pip install clique
If the Cheeseshop (a.k.a. PyPI) is down, you can also install Clique from one of the mirrors:
$ pip install --use-mirrors clique
Alternatively, you may wish to download manually from Github where Clique is actively developed.
You can clone the public repository:
$ git clone git://github.com/4degrees/clique.git
Or download an appropriate tarball or zipball
Once you have a copy of the source, you can embed it in your Python package, or install it into your site-packages:
$ python setup.py install
