+:mod:`packaging` --- Packaging support
+======================================
+
+.. module:: packaging
+   :synopsis: Packaging system and building blocks for other packaging systems.
+.. sectionauthor:: Fred L. Drake, Jr. <fdrake@acm.org>, distutils and packaging
+                   contributors
+
+
+The :mod:`packaging` package provides support for building, packaging,
+distributing and installing additional projects into a Python installation.
+Projects may include Python modules, extension modules, packages and scripts.
+:mod:`packaging` also provides building blocks for other packaging systems
+that are not tied to the command system.
+
+This manual is the reference documentation for those standalone building
+blocks and for extending Packaging. If you're looking for the user-centric
+guides to install a project or package your own code, head to `See also`__.
