They will be installed automatically when the package is installed. If you wish to use packages that are not available in PyPI, or want to give your users an alternate download location, you can add a 'find_links' option to the '[easy_install]' section of your project's 'setup.cfg' file, and then setuptools will scan the listed web pages for links that satisfy the requirements. 'extras_require' -- a dictionary mapping names of optional "extras" to the additional requirement(s) that using those extras incurs. For example, this:: extras_require = dict(reST = ["docutils>=0.3", "reSTedit"]) indicates that the distribution can optionally provide an extra capability called "reST", but it can only be used if docutils and reSTedit are installed. If the user installs your package using EasyInstall and requests one of your extras, the corresponding additional requirements will be installed if needed. 'package_data' -- a dictionary mapping package names to lists of filenames or globs to use to find data files contained in the named packages. If the dictionary has filenames or globs listed under '""' (the empty string), those names will be searched for in every package, in addition to any names for the specific package. Data files found using these names/globs will be installed along with the package, in the same location as the package. Note that globs are allowed to reference the contents of non-package subdirectories, as long as you use '/' as a path separator. (Globs are automatically converted to platform-specific paths at runtime.) In addition to these new keywords, this class also has several new methods for manipulating the distribution's contents. For example, the 'include()' and 'exclude()' methods can be thought of as in-place add and subtract commands that add or remove packages, modules, extensions, and so on from the distribution.
