;-------- NOW HERE IS THE QUESTION. PLEASE ANSWER USING THIS SCRIPT --------;
;---------------------------------------------------------------------------;
;---------------------------------------------------------------------------;
; I left off The Un.onInit for Someone to Help Me Understand Section Flags  ;
; So That Section that is needed to Fully get this to Work would need to be ;
; Written by Somebody Who knows. Adding Code to what is Needed and Posting  ;
; back on the Winamp.com NSIS Forum Where you Found this File. So to start  ;
; For the Purpose of Telling me how to Do what I Wanted to Understand Using ;
; These Section Names Please Show me How to do What I am Trying to do.      ;
;                                                                           ;
; Section1                                                                  ;
; Section2                                                                  ;
; Section3                                                                  ;
; Section4                                                                  ;
;                                                                           ;
; Using IfFileExists Could I Request if Whether or not Readme_01.txt or     ;
; Readme_02.txt Is there... If one is not than the UnInstaller Will Remove  ;
; That Section. So if Only Readme_01.txt Is Found it will Not Show Section4 ;
; on the Uninstallers List. That is about it... I have no idea how to Go    ;
; about it to where this Can be Achieved.. Even if to Go about it in a      ;
; Different way.                                                            ;
