:mod:`distutils` --- Building and installing Python modules
===========================================================

.. module:: distutils
   :synopsis: Support for building and installing Python modules into an
              existing Python installation.
.. sectionauthor:: Fred L. Drake, Jr. <fdrake@acm.org>


The :mod:`distutils` package provides support for building and installing
additional modules into a Python installation.  The new modules may be either
100%-pure Python, or may be extension modules written in C, or may be
collections of Python packages which include modules coded in both Python and C.

Most Python users will *not* want to use this module directly, but instead
use the cross-version tools maintained by the Python Packaging Authority. In
particular,
`setuptools <https://setuptools.pypa.io/en/latest/setuptools.html>`__ is an
enhanced alternative to :mod:`distutils` that provides:

* support for declaring project dependencies
* additional mechanisms for configuring which files to include in source
  releases (including plugins for integration with version control systems)
* the ability to declare project "entry points", which can be used as the
  basis for application plugin systems
* the ability to automatically generate Windows command line executables at
  installation time rather than needing to prebuild them
* consistent behaviour across all supported Python versions

The recommended `pip <https://pip.pypa.io/>`__ installer runs all
``setup.py`` scripts with ``setuptools``, even if the script itself only
imports ``distutils``. Refer to the
`Python Packaging User Guide <https://packaging.python.org>`_ for more
information.

For the benefits of packaging tool authors and users seeking a deeper
understanding of the details of the current packaging and distribution
system, the legacy :mod:`distutils` based user documentation and API
reference remain available:
