+\section{THE DRAGON PACKAGE}\label{sect:DragonExportPackage}
+
+The following archive is required to install DRAGON:
+
+\begin{verbatim}
+Version5_evn.tgz
+\end{verbatim}
+
+\vskip 0.08cm
+
+Information is recovered from the archive using
+\begin{verbatim}
+tar xvfz Version5_evn.tgz
+\end{verbatim}
+
+\noindent The {\tt tar xvfz} operations will create a directory named {\tt Version5\_evn}. Another directory named {\tt
+libraries} should also be created at the same level to hold cross section libraries. Directory {\tt libraries} is
+generally a symbolic link to an existing location. The complete setup is depicted in \Fig{tree2}.

+\end{figure}
+
+Directory {\tt Version5} contains the information required to install and configure
+DRAGON. It is a copy of the {\sl Subversion Working Copy} used by the developers of the
+code. Inside {\tt Version5\_evn} is a file named {\tt readme} that contain the
+information required to configure DRAGON on your system. This configuration
+process has the effect to add a few directories and binary files to the
+{\tt Version5\_evn} directory.
+
+\vskip 0.08cm
+
+Starting with version 5.0.5, it is possible to perform a basic installation on a Unix-based system
+using makefiles. {\sl Note:} On AIX and Solaris OS, you must replace {\tt make} with {\tt gmake} (the
+GNU variant of {\tt make} utility). To install Dragon, simply do
+\begin{verbatim}
+cd ~/Version5_evn/Dragon/
+make
+make clean
+\end{verbatim}
+
+\noindent To build an OpenMP-enabled version, simply write
+\begin{verbatim}
+make openmp=1
+\end{verbatim}
+
+\noindent To build an HDF5-enabled version, simply write
+\begin{verbatim}
+make hdf5=1
+\end{verbatim}
+
+\noindent To execute the Dragon non-regression tests, do
+\begin{verbatim}
+make tests
+\end{verbatim}
+

+
+On Windows, Version5 components an be build in two possible ways:
+\begin{itemize}
+\item  A native build is possible, provided that {\sl Microsoft Visual Studio} and {\sl Intel Visual Fortran} are available.
+A script named {\tt instver5.bat} is available to create executables ({\tt .exe}) from a MS-DOS command
+window. Follow the following steps:
+\begin{itemize}
+\item Click {\sl Start}, point to {\sl All Programs}, {\sl Intel(R) Software Development Tools}, {\sl Intel(R) Visual Fortran
+Compiler Professional} and finally {\sl Fortran Build Environment for applications running on IA-32}. The Visual Studio Command Prompt
+automatically sets the correct paths of both C and Fortran compilers, together with their associated libraries.
+\item In the command window, type:
+\begin{verbatim}
+md %homepath%\Version5_evn\
+\script\instver5
+\end{verbatim}
+\end{itemize}
+\item  A ``Unix-type" build is possible, provided that Cygwin\cite{cygwin} or {\sl Windows Subsystem for Linux} (WSL)\cite{wsl} is
+properly installed on your PC. Cygwin and WSL are native implementations of a {\sl Unix shell}. After installation of Cygwin or WSL, you
+obtain a native Unix terminal window where all Version5 components can be executed. The DRAGON installation must proceed in the shell.
+\end{itemize}
+
+\vskip 0.08cm
+
+Directory {\tt libraries} contains open-source Draglibs that can be used to
+test your implementation. This directory must me installed as shown in \Fig{tree2}
+{\sl before} following the instructions of the {\tt readme} file for executing
+multigroup tests. The script named
+{\tt tdraglib.access} is automatically executed by the {\tt rdragon} script when
+no other {\tt *.access} script is provided. The {\tt tdraglib.access} script creates
+a symbolic link between the draglib {\tt draglibJef2p2} and file {\tt DLIB\_J2}
+used in the {\tt tdraglib.x2m} and {\tt trowland.x2m} non-regression tests.
