Each of these packages is available in several formats. The source distribution is a complete set of documentation, tests, and the source files themselves. There are also two “Egg” files: these are files easy_install can install directly into your site-packages/ directory, and are Python-version specific. The download files for the latest version are always located on the Cheese Shop pages (listed below).
All the packages are available in the Mercurial repositories rooted in http://bitbucket.org/ianb/
