-PIL_ is almost dead, the last release was in 2009. If possible you should
-prefer to use Pillow_, a fork of PIL which is actively developped, with
-packaging improvements, Python 3 compatibility, etc.
-
-You can install Pillow with ``pip install Pillow``, preferably in a
-virtualenv_. To have JPG and PNG support, you must first install the
-developpement packages of libjpeg, freetype2 and zlib.
-
-- For Debian/Ubuntu, this is possible with::
-
-    apt-get build-dep python-dev python-imaging
-
-  Debian/Sid users can use the experimental ``python-imaging`` package that is
-  built from Pillow source.
-
-- For Archlinux, there is a package_ for sigal in the AUR which already uses
-  Pillow.
