- <h2>Python</h2>
-
- Python is an interpreted, interactive, object-oriented programming
- language often compared to Tcl, Perl, Scheme, or Java.
-
- <p> Python combines remarkable power with very clear syntax. It has
- modules, classes, exceptions, very high level dynamic data types, and
- dynamic typing. There are interfaces to many system calls and
- libraries, and new built-in modules are easily written in C or
- C++. Python is also usable as an extension language for applications
- that need a programmable interface. <p>
-
- <h2>wxWindows</h2>
-
- wxWindows is a free C++ framework designed to make cross-platform
- programming child's play. Well, almost. wxWindows 2 supports Windows
- 3.1/95/98/NT, Unix with GTK/Motif/Lesstif, with a Mac version
- underway. Other ports are under consideration. <p>
-
- wxWindows is a set of libraries that allows C++ applications to
- compile and run on several different types of computers, with minimal
- source code changes. There is one library per supported GUI (such as
- Motif, or Windows). As well as providing a common API (Application
- Programming Interface) for GUI functionality, it provides
- functionality for accessing some commonly-used operating system
- facilities, such as copying or deleting files. wxWindows is a
- 'framework' in the sense that it provides a lot of built-in
- functionality, which the application can use or replace as required,
- thus saving a great deal of coding effort. Basic data structures such
- as strings, linked lists and hash tables are also supported.
-
- <p>
- <h2>wxPython</h2>
-
- wxPython is a Python extension module that encapsulates the wxWindows
- GUI classes. Currently it is only available for the Win32 and GTK
- ports of wxWindows, but as soon as the other ports are brought up to
- the same level as Win32 and GTK, it should be fairly trivial to
- enable wxPython to be used with the new GUI.
-
- <p>
-
- The wxPython extension module attempts to mirror the class heiarchy
- of wxWindows as closely as possible. This means that there is a
- wxFrame class in wxPython that looks, smells, tastes and acts almost
- the same as the wxFrame class in the C++ version. Unfortunately,
- because of differences in the languages, wxPython doesn't match
- wxWindows exactly, but the differences should be easy to absorb
- because they are natural to Python. For example, some methods that
- return multiple values via argument pointers in C++ will return a
- tuple of values in Python.
-
- <p>
-
- There is still much to be done for wxPython, many classes still need
- to be mirrored. Also, wxWindows is still somewhat of a moving target
- so it is a bit of an effort just keeping wxPython up to date. On the
- other hand, there are enough of the core classes completed that
- useful applications can be written.
-
- <p>
-
- wxPython is close enough to the C++ version that the majority of
- the wxPython documentation is actually just notes attached to the C++
- documents that describe the places where wxPython is different. There
- is also a series of sample programs included, and a series of
- documentation pages that assist the programmer in getting started
- with wxPython.

+<h2>wxPython</h2>
+
+<p> wxPython is a <b>GUI toolkit</b> for the <a
+href="http://www.python.org/">Python</a> programming language. It
+allows Python programmers to create programs with a robust, highly
+functional graphical user interface, simply and easily. It is
+implemented as a Python extension module (native code) that wraps the
+popular <a href="http://wxwindows.org/front.htm">wxWindows</a> cross
+platform GUI library, which is written in C++.
+
+<p> Like Python and wxWindows, wxPython is <b>Open Source</b> which
+means that it is free for anyone to use and the source code is
+available for anyone to look at and modify. Or anyone can contribute
+fixes or enhnacments to the project.
+
+<p> wxPython is a <b>cross-platform</b> toolkit. This means that the
+same program will run on multiple platforms without modification.
+Currently supported platforms are 32-bit Microsoft Windows, most Unix
+or unix-like systems, and Macintosh OS X. Since the language is
+Python, wxPython programs are <b>simple, easy</b> to write and easy to
+understand.
+
+<p> <b>This demo</b> is not only a collection of test cases for
+wxPython, but is also designed to help you learn about and how to use
+wxPython. Each sample is listed in the tree control on the left.
+When a sample is selected in the tree then a module is loaded and run
+(usually in a tab of this notebook,) and the source code of the module
+is loaded in another tab for you to browse and learn from.
