+Pynsist
+^^^^^^^
+
+`Pynsist <https://pypi.python.org/pypi/pynsist>`__ is a tool that bundles Python
+programs together with the Python-interpreter into a single installer based on
+NSIS. In most cases, packaging only requires the user to choose a version of
+the Python-interpreter and declare the dependencies of the program. The tool
+downloads the specified Python-interpreter for Windows and packages it with all
+the dependencies in a single Windows-executable installer.
+
+The installer installs or updates the Python-interpreter on the users system,
+which can be used independently of the packaged program. The program itself,
+can be started from a shortcut, that the installer places in the start-menu.
+Uninstalling the program leaves the Python installation of the user intact.
+
+A big advantage of pynsist is that the Windows packages can be built on Linux.
+There are several examples for different kinds of programs (console, GUI) in
+the `documentation <http://pynsist.readthedocs.org>`__. The tool is released
+under the MIT-licence.
