+<i>
+To enable GTNetS model inside SimGrid it is needed to patch the GTNetS simulator source code
+and build/install it from scratch
+</i>
+
+ - <b>Download and enter the recent downloaded GTNetS directory</b>
+
+ \verbatim
+ svn checkout svn://scm.gforge.inria.fr/svn/simgrid/contrib/trunk/GTNetS/
+ cd GTNetS
+ \endverbatim
+
+
+ - <b>Use the following commands to unzip and patch GTNetS package to work within SimGrid.</b>
+
+ \verbatim
+ unzip gtnets-current.zip
+ cd gtnets-current
+ cp ../KAYO-PATCH-Added-RunUntilNextCompletion-and-some.patch .
+ cat .patch | patch -p1
+ \endverbatim
+
+ - <b>Compile GTNetS</b>
+
+ Due to portability issues it is possible that GTNetS does not compile in your architecture. Some
+ other patches are provided in GTNetS directory. Use those patches at your own risk.
+
+ \verbatim
+ cd gtnets-current
+ ln -sf Makefile.linux Makefile
+ make depend
+ make debug
+ \endverbatim
+
+ - If you have a problem compiling the GTNetS simulator a series of patches can be found <a href="http://mescal.imag.fr/membres/pedro.velho/simgrid/gtnets-current-patch.tgz">here</a>. Although, it is not
+guaranteed that these patches will make GTNetS compile in your architecture, they will just probably fix main issues when using the
+linux operating system.
+</p>
+
+ - <b>NOTE</b> A lot of warnings are expected but the application should compile
+ just fine. If the makefile insists in compiling some QT libraries
+ please try a make clean before asking for help.
+
+
+ - <b>To compile optimized version</b>
+
+ \verbatim
+ make opt
+ \endverbatim
+
+
+ - <b>Installing GTNetS</b>

+ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/<userhome>/usr/lib/libgtnets.so
+ mkdir /<userhome>/usr/include/gtnets
+ cp -fr SRC/*.h /<userhome>/usr/include/gtnets
+ \endverbatim
+
+
+ - <b>Enable GTNetS support in SimGrid</b>
+
+ \verbatim
+ ./configure --with-gtnets=/<userhome>/usr
+ \endverbatim
+
+ - <b>Once you have followed all the instructions for compiling and
+ installing successfully you can activate this feature at
+ runntime with the following options:</b>
