Python Packaging Library
Distutils2 development is stopped.
tl;dr: keep using setuptools and pip for now, don’t use distutils2.
Distutils2 tried to be all things to all people; Python core developers and developers of packaging tools have a different strategy to improve packaging. First, various features are discussed and integrated into Python on their own, such as namespace packages and virtual environments (Python 3.3). Second, a new format is defined for binary distibutions (wheel). Third, pip is blessed as de facto standard installer and installed with Python (3.4). Ongoing, new PEPs are in progress to make version numbers more robust, metadata more comprehensive, wheels usable on more platforms, build tools more flexible, etc. Other efforts like conda, bento, hashdist or pyinstaller may serve different needs of specific Python communities better.
Older description follows.
Welcome to Distutils2
Distutils2 is the packaging library that supersedes Distutils. It has three main audiences:
Python authors who want to distribute their code
End users who want to install modules or applications
Developers of packaging-related tools who need a support library to build on
Authors will have to write a setup.cfg file and run a few commands to package and distribute their code. End users will be able to search for, install and remove Python projects with the included pysetup program. Last, developers will be able to reuse classes and functions in their tools.
The Distutils2 codebase is a fork of Distutils. It is not backward compatible with Distutils and does not depend on it. It provides more features and implements new packaging standards. In Python 3.3, Distutils2 is included in the standard library under the module name “packaging”. Documentation is provided at http://docs.python.org/dev/packaging –for ease of maintenance, it is not duplicated in this repository. You can use the Packaging documentation to use Distutils2; only the package name is different (packaging vs. distutils2), all modules, classes and functions have the same name.
If you want to contribute, please have a look at DEVNOTES.txt or http://wiki.python.org/Distutils2/Contributing .
Beware that Distutils2 is still in alpha stage and its API is subject to change. It should be not used for critical deployments. That said, it is possible to start using it while keeping compatiblity with tools based on the old Distutils or Setuptools, and the developers are eager to get feedback from authors, end users and developers.
