This fruit basket program is written in JavaScript, one of the most widely
used programming languages due to its presence on the web.  The program is
run with an interpreter called wxJavaScript, available at
http://www.wxjavascript.net

This interpreter is based on the SpiderMonkey JavaScript engine developed
by the Mozilla Foundation at
https://developer.mozilla.org/en/SpiderMonkey

wxJavaScript is compiled with Visual C++ 2008 Express.  The executable
depends on C++ runtime files.  If you do not already have them installed,
you can download the Visual C++ 2008 Redistributable Package from
http://www.microsoft.com/downloads/details.aspx?familyid=9B2DA534-3E03-4391-8A4D-074B9F2BC1BF&displaylang=en

The interpreter includes a module that wraps the wxWidgets GUI library
developed at
http://wxWidgets.org

Other modules are also part of the package, including MySQL and SQLite.

This archive includes a batch file, run.bat, for running the fruit basket
program with the interpreter.  The source code, wxjs_fruit.js, is also
pasted below.  The interpreter can also be run in an interactive mode for
testing expressions in JavaScript.  Text tutorials on this language are
included in the archive
