iTunes Folder-Sync
By: Gareth Farrington
From: http://www.waves.ky/iTunes/iTunesFolderSync.js
Version: 0.2
License: This is Freeware. No Warrantees are given or implied.

	* Find new tracks in the folders where you store your music (e.g. new rips, downloads, podcasts)
	* Make it easy to store your music any way you like
	* remove tracks from iTunes Library that are no longer on disk (e.g. you deleted or renamed a track)
	* update your iPod when everything is done
	
	Note on Converting Songs prompt:
	During the sync you you may be asked to convert tracks in WMA format to something iTunes can play. If you have 
	already converted tracks duplicates will be created! I suggest just pressing skip to avoid this.

0.2 - 3/Oct/2005
	+ Support for specifying your own music folders
	+ Ignores sub folders that fall under user defined music folders
	+ Batch import, shows progress bar correctly
	+ Runs Faster
	
0.1 - original version
	+ Discover new songs to import
	+ Sync iPod when finished

 * Follow the format carefully, each directory seperator needs to be a double slash "\\".
 * Seperate each entry with a comma.
