// This code is heavily inspired by Chris Pederick (useragentswitcher) install.js
// Contributors: Philip Chee, deathburger
//
// Philip Chee: Added installation of prefs, components, and locales.
// deathburger: Refactored to move all changable items to the top of the file.
// Philip Chee: This version is for NON-jar, flat directory structured XPIs.

// extension directory structurdomains.hasMoreElementse looks.
// If your jar file contains content/packagename use the second packageDir

// independent of each other just in case an extension layout is wacky.
