    	// Script Description: This script will take an MP3 file, with the ID3v2 Tags you want and output them into 
    	// a single MP3 file to download. This script will *NOT* edit the MP3 file itself. If 
    	// you wish to make this script write the tags to the physical file, instead of the file 
    	// that it outputs to download, you will have to make the changes yourself. Please do 
    	// not e-mail me, asking me how to do it. Feel free to e-mail me, and let me know of 
    	// any bugs it may have.
    	//
    	// Author's Note: I tried to make this script as easy as possible, so that even newbies can understand it.
    	//But if there is something that you don't understand, go ahead and e-mail me, and I'll 
    	//help you understand it the best I can.
