-can be used for any window);
-\item wxMultiText, wxTextWindow, wxText removed and replaced by wxTextCtrl;
-\item classes no longer divided into generic and platform-specific parts, for efficiency.
-\end{itemize}
-
-Additions and changes:
-
-\begin{itemize}\itemsep=0pt
-\item class hierarchy changed, and restrictions about subwindow nesting lifted;
-\item header files reorganized to conform to normal C++ standards;
-\item classes less dependent on each another, to reduce executable size;

-below the utils directory and usually have their own source, library

-\section{wxHelp}\label{wxhelp}
-
-wxHelp is a stand-alone program, written using wxWindows,
-for displaying hypertext help. It is necessary since not all target
-systems (notably X) supply an adequate
-standard for on-line help. wxHelp is modeled on the MS Windows help
-system, with contents, search and browse buttons, but does not reformat
-text to suit the size of window, as WinHelp does, and its input files
-are uncompressed ASCII with some embedded font commands and an .xlp
-extension. Most wxWindows documentation (user manuals and class
-references) is supplied in wxHelp format, and also in Windows Help
-format. The wxWindows 2.0 project will presently use an HTML widget
-in a new and improved wxHelp implementation, under X.
-
-Note that an application can be programmed to use Windows Help under
-MS Windows, and wxHelp under X. An alternative help viewer under X is
-Mosaic, a World Wide Web viewer that uses HTML as its native hypertext
-format. However, this is not currently integrated with wxWindows
-applications.
-
-wxHelp works in two modes---edit and end-user. In edit mode, an ASCII
-file may be marked up with different fonts and colours, and divided into
-sections. In end-user mode, no editing is possible, and the user browses
-principally by clicking on highlighted blocks.
-
-When an application invokes wxHelp, subsequent sections, blocks or
-files may be viewed using the same instance of wxHelp since the two
-programs are linked using wxWindows interprocess communication
-facilities. When the application exits, that application's instance of
-wxHelp may be made to exit also.  See the {\bf wxHelpControllerBase} entry in the
-reference section for how an application controls wxHelp.

-\section{Tex2RTF}\label{textortf}
-
-Supplied with wxWindows is a utility called Tex2RTF for converting\rtfsp
-\LaTeX\ manuals to the following formats:
-
-\begin{description}
-\item[wxHelp]
-wxWindows help system format (XLP).
-\item[Linear RTF]
-Rich Text Format suitable for importing into a word processor.
-\item[Windows Help RTF]
-Rich Text Format suitable for compiling into a WinHelp HLP file with the
-help compiler.
-\item[HTML]
-HTML is the native format for Mosaic, the main hypertext viewer for
-the World Wide Web. Since it is freely available it is a good candidate
-for being the wxWindows help system under X, as an alternative to wxHelp.
-\end{description}
-
-Tex2RTF is used for the wxWindows manuals and can be used independently
-by authors wishing to create on-line and printed manuals from the same\rtfsp
-\LaTeX\ source.  Please see the separate documentation for Tex2RTF.
-
-\section{wxTreeLayout}
-
-This is a simple class library for drawing trees in a reasonably pretty
-fashion. It provides only minimal default drawing capabilities, since
-the algorithm is meant to be used for implementing custom tree-based
-tools.
-
-Directed graphs may also be drawn using this library, if cycles are
-removed before the nodes and arcs are passed to the algorithm.
-
-Tree displays are used in many applications: directory browsers,
-hypertext systems, class browsers, and decision trees are a few
-possibilities.
+In addition to the core wxWindows library, a number of further
+libraries and utilities are supplied with each distribution.

 
 

-See the separate manual and the directory utils/wxtree.
+Some are under the 'contrib' hierarchy which mirrors the
+structure of the main wxWindows hierarchy. See also the 'utils'
+hierarchy. The first place to look for documentation about
+these tools and libraries is under the wxWindows 'docs' hierarchy,
+for example \verb$docs/htmlhelp/fl.chm$.

 
 

-\section{wxGraphLayout}
+For other user-contributed packages, please see the Contributions page
+on the \urlref{wxWindows Web site}{http://www.wxwindows.org}.

 
 

-The wxGraphLayout class is based on a tool called `graphplace' by Dr.
-Jos T.J. van Eijndhoven of Eindhoven University of Technology. Given a
-(possibly cyclic) directed graph, it does its best to lay out the nodes
-in a sensible manner. There are many applications (such as diagramming)
-where it is required to display a graph with no human intervention. Even
-if manual repositioning is later required, this algorithm can make a good
-first attempt.
+\begin{description}\itemsep=0pt
+\item[{\bf Helpview}]
+Helpview is a program for displaying wxWindows HTML
+Help files. In many cases, you may wish to use the wxWindows HTML
+Help classes from within your application, but this provides a
+handy stand-alone viewer. See \helpref{wxHTML Notes}{wxhtml} for more details.
+You can find it in \verb$samples/html/helpview$.

+\LaTeX\ source. Please see the separate documentation for Tex2RTF.
+You can find it under \verb$utils/tex2rtf$.
+
+\item[{\bf Helpgen}]
+Helpgen takes C++ header files and generates a Tex2RTF-compatible
+documentation file for each class it finds, using comments as appropriate.
+This is a good way to start a reference for a set of classes.
+
+\item[{\bf Dialog Editor}]
+Dialog Editor allows interactive construction of dialogs using
+absolute positioning, producing WXR output files. This tool is generally deprecated
+in favour of sizer-based tools. You can find Dialog Editor
+in \verb$utils/dialoged$.
+
+\item[{\bf XRC resource system}]
+This is the sizer-aware replacement for the WXR resource system, and uses
+XML-based resource specifications that can be generated by tools
+such as \urlref{wxDesigner}{http://www.roebling.de} and XRC's own wxrcedit.
+You can find this in \verb$contrib/src/xrc$, \verb$contrib/include/wx/xrc$, \verb$contrib/samples/xrc$, and \verb$contrib/utils/wxrcedit$.
+For more information, see the \helpref{XML-based resource system overview}{xrcoverview}.
+
+\item[{\bf Object Graphics Library}]
+OGL defines an API for applications that need to display objects connected by lines.
+The objects can be moved around and interacted with.
+You can find this in \verb$contrib/src/ogl$, \verb$contrib/include/wx/ogl$, and \verb$contrib/samples/ogl$.
+
+\item[{\bf Frame Layout library}]
+FL provides sophisticated pane dragging and docking facilities.
+You can find this in \verb$contrib/src/fl$, \verb$contrib/include/wx/fl$, and \verb$contrib/samples/fl$.

+there is only wxEmail, which makes it easy to send email messages via MAPI on Windows or sendmail on Unix.
+You can find this in \verb$contrib/src/net$ and \verb$contrib/include/wx/net$.
+
+\item[{\bf Animate library}]
+Animate allows you to load animated GIFs and play them on a window. The library can be extended
+to use other animation formats.
+You can find this in \verb$contrib/src/animate$, \verb$contrib/include/wx/animate$, and \verb$contrib/samples/animate$.
