+This example shows how to package a program that uses the PyGI-bindings of Gtk (or PyGObject). Python 3.4.3 64-bit will be used together with 64-bit dependencies.
+
+The example program conists of a window with a matplotlib-plot and a button that triggers the window to close.
+
+Requirements
+------------
+
+This example needs 7zip in order to work. You can install it for example on
+Debian-style distributions using:
+
+::
+
+    sudo apt-get install p7zip
+
+Building the program
+--------------------
+
+A shell script can be used to download some of the dependencies:
+
+::
+
+    sh 1_download.sh
+
+The numpy 64-bit wheel can be downloaded here (numpy‑1.9.2+mkl‑cp34‑none‑win_amd64.whl):
+
+http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy
+
+Rename it to numpy.whl before starting the second script.
+
+The next script will copy all the dependencies into the ``pynsist_pkgs`` folder.
+
+::
+
+    sh 2_extract.sh
+
+After that, the example can be built using this command:
+
+::
+
+    python3 -m nsist installer.cfg
+
+Installer.cfg
+-------------
+
+The example uses 64-bit Python 3.4 and 64-bit dependencies. This is expressed in the
+``installer.cfg``-file like this:
+
+::
+
+    version=3.4.3
+    bitness=64
+
+The include section requires the Python packages numpy, matplotlib (which are taken from the ``pynsist_pkgs`` folder). In addition the packages six, dateutil and pyparsing are required. From the pygi-bindings the top level packages cairo, dbus, gi, gnome and pygtkcompat have to be listed here (They are also in the top level of the ``pynsist_pkgs`` directory). The ``gnome``-folder contains the dependencies ATK, Base, GDK, GDKPixbuf, GTK, JPEG, Pango, WebP and TIFF.
