+\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).
+ \end{itemize}

+\subsubsection{Boxes Help}
+% ==========================================
+ Box retrieving on various criteria :
+ \begin{itemize}
+ \item {\bf\emph{Alphabetical list}} \\ This is the 'zero-level' of retrieving.
+ \item {\bf\emph{List by package}} \\ Several packages are supplied with bbtk :
+ \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{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{\texttt{GUICreateBlackBox}} For creating the XML or C++ code for a new black box
+ \item{\texttt{GUICreatePackage}} For creating a new bbtk package file structure on disk (Graphical user interface for the shell script bbCreatePackage)
+ \item{\texttt{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}}.
+
+
+ A given box may belong to more than one \texttt{category}.\\
+ You have to consider categories like keywords to index black boxes.\\
+ Some of them are mutually exclusive.
+ A black box may be :
+ \begin {itemize}
+ \item{atomic box / complex box}\\
+ Whether it's written is C++ or it's an assembly of several black boxes (atomic or complex).\\
+ Any box is either atomic ou complex.
+ \item{example / demo / application}\\
+ These ones are always complex black boxes.
+ \begin {itemize}
+ \item{example}\\
+ It's just a (simple) example, for programmers, on how to use a given feature.
+ \item{demo}\\
+ It can be a 'good looking' (a.k.a 'sexy') example on some sophisticated work.
+ \item{application}\\
+ It's a Final application, end user intended (e.g. Subscale a huge volume, Crop a DICOM image, etc)
+ \end {itemize}
+ \item{widget}\\
+ Piece of graphical interface (based on \texttt{wxWidgets})
+ \item{Dicom}\\
+ Dicom medical image related box.
+ \item{viewer}\\
+ \item{read/write}
+ \item{mesh}
+ \item{3D Object creator}
+ \item{math}
+ \item{misc}
+ \end {itemize}
