+\subsubsection{Guides}
+% ==========================================
+
+An html version of all the guides is browsable in the \texttt{Help} part of \bbStudions.
+ \begin{itemize}
+ \item {\bf\emph{User's Guide}} : Step to step How-to for user who wants to create his own
+ application, just using already existing boxes.
+ \item {\bf\emph{Package Developper's Guide}} : Step to step How-to for programmer who wants to create his own
+ black boxes/packages.
+ \item {\bf\emph{Developper's Guide}} : For bbtk kernel developpers only. (This one is probabely not very much
+ up-to-date, since we spend more time in developping than writing documentation that's not of user concern).
+ \item {\bf\emph{Reference Manual}} : Contains a exaustive description of all the features for all the commands.
+ \item {\bf\emph{Booklet}} : Vade mecum.
+ \item {\bf\emph{Doxygen Documentation}} : Doxygen source browser.\\ Automatically generated from source file
+ headers. Should concern only the kernel developpers (i.e. : us).

+ \begin{itemize}
+ \item {\bf\emph{std}} : the 'standard' package including basic useful boxes.
+ \item {\bf\emph{wx}} : basic graphical interface elements (widgets : sliders, buttons, etc. based on the \texttt{wxWidgets} library).
+ \item {\bf\emph{itk}} : the basic image processing package, based on the \itk library.
+ \item {\bf\emph{vtk}} : the basic images and surfaces processing and vizualization package, based on the \vtk library.
+ \item {\bf\emph{wxvtk}} : widget boxes based on the \vtk library (2D and 3D vizualization and
+ interaction).
+ \item {\bf\emph{itkvtk}} : special boxes (adaptors) to convert \itk structures into \vtk structures and conversally.
+ %\item {\bf\emph{creaImageIO}} : Provides hight level widgets to read images, including DICOM.
+ \item {\bf\emph{toolsbbtk}} : Tools for bbtk administration and package development, such as :
+ \begin{itemize}
+ \item{GUICreateBlackBox} For creating the XML or C++ code for a new black box
+ \item{GUICreatePackage} For creating a new bbtk package file structure on disk (Graphical user interface for the shell script bbCreatePackage)
+ \item{MakePackageDoc} For creating the html documentation of a package. The doc is generated at the 'canonical' location. Works both for a build tree or an installed toolkit.
+ \end{itemize}
+ \end{itemize}
+ \item {\bf\emph{{List by category}}.
