-Generate and upload the Windows installer
-=========================================
-
-We are now able to build and distribute an MSI installer for Windows,
-assuming that Anaconda is the installed Python distribution. This
-installer is generated by `WiX`_ from an XML file, stored in the
-`Theano-wininstaller <https://github.com/Theano/Theano-wininstaller>`__
-Git repository.
-
-* Install `WiX`_ if it is not already installed.
-
-* On a Windows machine, checkout the ``Theano-wininstaller`` repository::
-
-    git checkout https://github.com/Theano/Theano-wininstaller.git
-
-* In ``Theano-wininstaller\src``, create a *new*
-  ``theano_installer_<version>.wxs`` from the previous one. We want to
-  keep a history of these files, as they contain globally unique IDs.
-
-* Change the strings and GUIDs appropriately, see `the WiX tutorial
-  <http://wix.tramontana.co.hu/tutorial/upgrades-and-modularization>`__
-  for a reference.
-
-* Compile the ``.wxs`` file following the instructions in it, it will be something like::
-
-    candle.exe theano_installer_<version>.wxs
-    light.exe -ext WixUIExtension theano_installer_<version>.wixobj
-
-  This will generate a ``theano_installer_<version>.msi`` file in ``src``.
-
-* Test it by trying to install and uninstall it. It can be done by
-  double-clicking on it, then uninstalling it from the Windows control
-  panel, or (more easily) from the command line, which also allows to
-  save the logs (use the ``*v`` modifier to increase verbosity)::
-
-    msiexec /i <file>.msi [/l[*v] install.log]
-    msiexec /x <file>.msi [/l[*v] uninstall.log]
-
-* When the test works, copy ``theano_installer_<version>.msi``
-  into ``Theano-wininstaller\bin``, overwrite
-  ``bin\theano_installer_latest.msi`` with another copy, then add the new
-  files into the Git repository, and push to master::
-
-    copy src\theano_installer_<version>.msi bin\
-    copy /y src\theano_installer_<version>.msi bin\theano_installer_latest.msi
-    git add src\theano_installer_<version>.wxs
-    git add bin\theano_installer_<version>.msi
-    git add bin\theano_installer_latest.msi
-    git commit
-    git push
