// XED is a cross-browser, cross-platform wysiwyg editor.  The name XED is
// pronounced like the letter "Z" (zed, not zee).
//
// Credits:
//
// - Much assistance has been privided by my patient sidekick:
//   Dynamic HTML: The Definitive Reference (O'Reilly, ISBN: 0-596-00316-1)
//   This book paid for itself twofold the first time I opened it.
//
// - Some plagiarism of code and ideas has occurred here, notably from the
//   following list of victims:
//
//   - htmlArea (http://www.interactivetools.com/products/htmlarea/) which
//     I probably would have simply customized this had it been around before
//     I started Xed, and I admit currently has some advantages over Xed.
//     Note: htmlArea is easily integrated into Sitellite anyway, so if you
//     like, use it in place of Xed.  No hard feelings...  However, Xed is
//     much prettier. ;)
