+To use a third party Package, you will have to update the \emph{bbtk\_config.xml} file.\\
+
+Just use the \texttt{Open bbtk Config file} option of the \texttt{Files} of the \bbStudio menu.
+
+You will get something like :
+\begin{verbatim}
+<config>
+ <description> Sets the search directories in the build tree </description>
+ <url> </url>
+ <bbs_path> /home/jpr/Creatis/bbtk/binLIN/share/bbtk/bbs </bbs_path>
+ <package_path> /home/jpr/Creatis/bbtk/binLIN/bin </package_path>
+# For windows
+ <package_path> /home/jpr/Creatis/bbtk/binLIN/bin\Debug </package_path>
+ <package_path> /home/jpr/Creatis/bbtk/binLIN/bin\Release </package_path>
+#
+ <data_path> </data_path>
+#
+ <default_temp_dir> /home/jpr/Creatis/bbtk/binLIN </default_temp_dir>
+</config>
+\end{verbatim}
+
+%\begin{itemize}
+%\item {
+After the already existing tags
+%bbs\_path
+\texttt{bbs\_path}
+ (i.e. the lines begining by
+ \texttt{bbs\_path}
+ %bbs_path
+and ending by
+\texttt{/bbs\_path})
+
+%/bbs_path})
+ add a new one with the name of the directory that contains the
+ \texttt{.bbs} scripts of the package you
+want to use.\\
+x
+%\item {
+After the already existing tags \texttt{package\_path} (i.e. the lines begining by \texttt{package\_path}
+ and ending by \texttt{/package\_path})
+ add a new one with the name of the directory that contains the the dynamic libraries
+ (\texttt{.dll} or \texttt{.so}) of the package you want to use.

+If you want (and sure you will) to be able to use the Help tools as well as the features provided by this package,
+ you must use the
+option \texttt{Regenerate package doc} in the menu \texttt{Tools} of \texttt{bbStudio}.\\
+You'll be prompted for the Package name. Avoid using the \texttt{-a} option (Regenerate all), since it's time consumming.
+
+If you want (and sure you will) to benefit the features of Box indexing
+ you must use the
+option \texttt{Regenerate Boxes Lists} in the menu \texttt{Tools} of \texttt{bbStudio}.\\
