// INTRODUCTION
//
// Well, hello there!
//
// Don't be scared! :-)
//
// This is the FiddlerScript Rules file, which creates some of the menu commands and
// other features of Fiddler. You can edit this file to modify or add new commands.
//
// The original version of this file is named SampleRules.js and it is in the
// \Program Files\Fiddler\ folder. When Fiddler first runs, it creates a copy named
// CustomRules.js inside your \Documents\Fiddler2\Scripts folder. If you make a 
// mistake in editing this file, simply delete the CustomRules.js file and restart
// Fiddler. A fresh copy of the default rules will be created from the original
// sample rules file.

// The best way to edit this file is to install the FiddlerScript Editor, part of
// the free SyntaxEditing addons. Get it here: http://fiddler2.com/r/?SYNTAXVIEWINSTALL

// GLOBALIZATION NOTE: Save this file using UTF-8 Encoding.
