// ==UserScript==
// @name           Create scriptwriter feed
// @namespace      http://esquifit.myopenid.com/
// @description    Create userscripts author feed via special YPipe + AppJet app
// @include        http://userscripts.org/users/*
// ==/UserScript==

/* Change log:
 * version 0.1:
   + Released in userscripts.org
 * version 0.2
   + Script runs now also on the "scripts" and "script comments" pages
   x Fix bug when detecting user's nick (don't use the word 'name' for a global variable,
     this is is the same as window.name and it is persisted across pages and windows!)
 * version 0.3
   x Backend AppJet engine is now hosted at jgate.de
 * version 0.4
   x Fix wrong urls passed to the feed generator when the user profile is invoked
     via user name instead of user id (for ex. http://userscripts.org/users/esquifit) 
   x Fix parsing of userID when profile page uses username instead of ID
   + Support for new user pages (guides, groups, jetpacks, etc)
