+Running 64bit Matlab on 32bit host OS
+=====================================
+
+Some of you have experienced problems due the recent move of Mathworks to
+drop 32-bit Linux builds of their products (i.e. Matlab R2013a and
+co.). Please note that this is not the first time Mathworks values its own
+costs higher than the benefits of a few scientists.  In 1998 PowerPC builds
+for Macs were abandoned, causing a `furious reaction
+<http://www.mathworks.com/matlabcentral/newsreader/view_thread/5910>`__
+of the community.
+
+Luckily, users of the fresh Debian stable release *wheezy* (or more recent
+variants of Debian and its derivatives) who still need a 32bit OS on
+64bit-capable hardware can take advantage of the new `multiarch
+<http://wiki.debian.org/Multiarch>`_ support.  Multiarch allows for
+multiple architecturesi to co-exist on a hardware/kernel
+that is capable of supporting both (e.g. i386 and amd64).
+
+Below we describe how you can use multiarch support and in few simple steps
+that prepare your existing 32bit user-land for running 64bit Matlab.
+
+
+Procedure
+---------
+
+- [2-10 min] Install 64-bit kernel and reboot::
+
+   sudo apt-get install linux-image-amd64
+
+- [1-3 min] Enable multi-arch support for amd64 architecture::
+
+   sudo dpkg --add-architecture amd64
+   sudo apt-get update
+
+- [1-5 min] Install 64bit libraries (and compilers) needed for matlab::
+
+   sudo apt-get install libstdc++6:amd64 zlib1g:amd64 libncurses5:amd64 \
+     libxp6:amd64 libstdc++6-4.4-dev:amd64 libxt6:amd64 libxmu6:amd64 libxtst6:amd64 \
+     g++:amd64 gcc:amd64 binutils:amd64
+
+Now your 64bit matlab (which you hopefully "registered" with
+:ref:`matlab-support <binary_pkg_matlab-support>`) is ready to run.
