+###############################
+  The Python Standard Library
+###############################
+
+While :ref:`reference-index` describes the exact syntax and
+semantics of the Python language, this library reference manual
+describes the standard library that is distributed with Python. It also
+describes some of the optional components that are commonly included
+in Python distributions.
+
+Python's standard library is very extensive, offering a wide range of
+facilities as indicated by the long table of contents listed below. The
+library contains built-in modules (written in C) that provide access to
+system functionality such as file I/O that would otherwise be
+inaccessible to Python programmers, as well as modules written in Python
+that provide standardized solutions for many problems that occur in
+everyday programming. Some of these modules are explicitly designed to
+encourage and enhance the portability of Python programs by abstracting
+away platform-specifics into platform-neutral APIs.
+
+The Python installers for the Windows platform usually include
+the entire standard library and often also include many additional
+components. For Unix-like operating systems Python is normally provided
+as a collection of packages, so it may be necessary to use the packaging
+tools provided with the operating system to obtain some or all of the
+optional components.
+
+In addition to the standard library, there is a growing collection of
+several thousand components (from individual programs and modules to
+packages and entire application development frameworks), available from
+the `Python Package Index <https://pypi.org>`_.
+
+.. We don't use :numbered: option for the TOC below as it enforces
+   numbered sections for the entire stdlib docs.  If desired,
+   :numbered: can be enabled on a per-module basis.
