; ----------------------------------------------------------------
; NOTE: this .nsi script was last built with 'makensis.exe' 
; version 1.98.  If you go to install it (unchanged) and get errors,
; try tracking down that older version, or try to figure out what
; has changed since then.  You can get NSIS at:
;
;               http://www.nullsoft.com/free/nsis/
; 
; This installer will produce a single EXE file that, when run, 
; will decompress and install your plugin and all of its data files 
; to Winamp 2 or Winamp 3.
; ----------------------------------------------------------------
; MODIFYING THIS SCRIPT TO CREATE AN INSTALLER FOR YOUR OWN PLUGIN:
; ----------------------------------------------------------------
;   1) there are three sections below, each marked 'EDIT THIS SECTION 
;        [x/3]' where 'x' is the section number.  These are the 3
;        places where you need to make changes to customize this
;        installer script for your particular plugin.  Go to each
;        and make the changes, reading the comments there for
;        more information.
;   2) download NSIS from http://www.nullsoft.com/free/nsis/, if you
;        haven't already.
;   3) run the command 'makensis.exe installer.nsi' to build
;        the executable.  (note: ignore the warning message about
;        'InstallRegKey' being used multiple times; this is necessary
;        to determine whether Winamp 2 or 3 is a better candidate
;        for the install.)
; ----------------------------------------------------------------
; WHAT THIS INSTALLER SCRIPT DOES:
; ----------------------------------------------------------------
;   If Winamp 2 is installed, it will install your plugin to Winamp 2, 
;   in the directory Winamp\Plugins (or whatever is specified as the 
;   vis plugins path, in Winamp\winamp.ini).  It will also select
;   the plugin as the current plugin.  (Note that Winamp must be
;   closed to do this, so if it's open, the installer will ask the 
;   user to close it before proceeding.)  At the end of a successful
;   install, it asks if they'd like to run Winamp.
; 
;   If Winamp 2 is not present but Winamp 3 is, or if the user manually
;   selects the Winamp 3 directory to install to, the plugin will be 
;   installed to Winamp 3 as a classic visualization plugin, to the 
;   directory Winamp3\Plugins.  At install time, if ClassicVis is not
;   installed, it will prompt the user to go download it.  If they
;   don't download it, it will tell them the installation failed.
;   If they already had it, or after they presumably download it,
;   the installer will briefly tell them how to select their new 
;   plugin and run it in Winamp 3, using ClassicVis.  Finally, at 
;   the end of a successful install, it asks if they'd like to run 
;   Winamp 3.
