For some operations Stéganô needs the Python Imaging Library (PIL):

    $ wget http://effbot.org/downloads/Imaging-1.1.7.tar.gz
    $ tar -xzvf Imaging-1.1.7.tar.gz
    $ rm -f Imaging-1.1.7.tar.gz
    $ cd Imaging-1.1.7/
    $ sudo python setup.py install
    $ cd ..
    $ sudo rm -Rf Imaging-1.1.7/



To install Stéganô:

    $ python setup.py install
