    Title: "Call Spellchecker"
    Version: 1.0.
    Author: "R. v.d.Zee"
    Rights: {Copyright © R. v.d.Zee 2006}
    Purpose: {The script provides a basic spell check for Rebol text areas.}
    Notes: {
    The Ispell spell checker will be shown in the shell.
    
    A similar script can be used with Windows XP, if Aspell has been installed.   
    There is a complete Aspell installer for Windows XP:
        http://ftp.gnu.org/gnu/aspell/w32/Aspell-0-50-3-3-Setup.exe 
        - from the web page http://aspell.net/win32/
        Only the one file, the installer, is needed.
    
    The call script might be a little different: 
    
        call [%aspell/bin/aspell check %rebol-spellcheck-testFile.txt]
        
    Presenting the spell checker output in a REBOL layout might be the next step....
