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. 'features' **deprecated** -- a dictionary mapping option names to 'setuptools.Feature' objects. Features are a portion of the distribution that can be included or excluded based on user options, inter-feature dependencies, and availability on the current system. Excluded features are omitted from all setup commands, including source and binary distributions, so you can create multiple distributions from the same source tree. Feature names should be valid Python identifiers, except that they may contain the '-' (minus) sign. Features can be included or excluded via the command line options '--with-X' and '--without-X', where 'X' is the name of the feature. Whether a feature is included by default, and whether you are allowed to control this from the command line, is determined by the Feature object. See the 'Feature' class for more information. 'test_suite' -- the name of a test suite to run for the 'test' command. If the user runs 'python setup.py test', the package will be installed, and the named test suite will be run. The format is the same as would be used on a 'unittest.py' command line. That is, it is the dotted name of an object to import and call to generate a test suite. '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. They are used by the feature subsystem to configure the distribution for the included and excluded features.

'standard' -- if true, the feature is included by default if it is available on the current system. Otherwise, the feature is only included if requested via a command line '--with-X' option, or if another included feature requires it. The default setting is 'False'. 'available' -- if true, the feature is available for installation on the current system. The default setting is 'True'. 'optional' -- if true, the feature's inclusion can be controlled from the command line, using the '--with-X' or '--without-X' options. If false, the feature's inclusion status is determined automatically, based on 'availabile', 'standard', and whether any other feature requires it. The default setting is 'True'. 'require_features' -- a string or sequence of strings naming features that should also be included if this feature is included. Defaults to empty list. May also contain 'Require' objects that should be added/removed from the distribution. 'remove' -- a string or list of strings naming packages to be removed from the distribution if this feature is *not* included. If the feature *is* included, this argument is ignored. This argument exists to support removing features that "crosscut" a distribution, such as defining a 'tests' feature that removes all the 'tests' subpackages provided by other features. The default for this argument is an empty list. (Note: the named package(s) or modules must exist in the base distribution when the 'setup()' function is initially called.) other keywords -- any other keyword arguments are saved, and passed to the distribution's 'include()' and 'exclude()' methods when the feature is included or excluded, respectively. So, for example, you could pass 'packages=["a","b"]' to cause packages 'a' and 'b' to be added or removed from the distribution as appropriate. A feature must include at least one 'requires', 'remove', or other keyword argument. Otherwise, it can't affect the distribution in any way. Note also that you can subclass 'Feature' to create your own specialized feature types that modify the distribution in other ways when included or excluded.
